NOTE: I am not an attorney, psychologist, counselor or therapist. These are simply my suggestions and thoughts having dealt with a bitter ex-wife for the last 3 years.
With the holiday season approaching & the economy tanking, I'm noticing more and more searches on dealing with a hostile ex wife. Lack of money does bring out the worst in people--as often do the holidays. So, for what it's worth, some idea that might help you survive the holidays.
1. Do not let the guilt of divorce lead you to be a bad parent. Too often divorced parents try to buy the child's affection, or buy things to interfere with the other parent. When we bought Andy's son a train set as a gift, the ex immediately had to buy the exact same one for him to have at her house. Children do not need 20 presents at Christmas. It can be really tempting to buy elaborate gifts out of guilt, but have you ever enjoyed being around a spoiled child? Doesn't the word "brat" spring to mind? Don't turn your own child into one. You are trying to raise a decent human being, not win a popularity contest.
2. You are not obligated to spend Christmas with people who make you unhappy. You have one person attached to your life who is horrible and mean--you don't need to accept any others. We were recently traveling on a commuter train, and all the talk of the holidays was not about the excitement or parties or even money--it was about family problems and obligations and not wanting to have to see certain relatives. If your family get-togethers are stressful or unpleasant, don't go. Being biologically linked to someone doesn't guarantee that you're going to like him or her.
3. Let others know what you're going through. Last year we had to made some very difficult decisions, and ones that were going to be hard for some people to accept. When explaining our decisions to some of the relatives, we actually sent an outline of everything we had tried to do over the last years--actually predating me & going back the full 5 years since the divorce--and simply attached a large sampling of the ex wife's abusive and spiteful emails and letters. In order to save face, Andy really hadn't ever been open about how bad the situation had gotten, though many of his family members suspected that it was much worse than he was letting on. It really helped to tear down some of the walls, though I think the shock of how nasty she actually has been was a bit overwhelming for some of them.
4. Consider giving Alec Baldwin's book as a gift. As a rule, I never read anything about celebrities because I think worshiping someone for being good at a job is a bit strange, but I did read this one and anyone who has gone through the hostile-ex drama will see his or her own story in it. He does have some great advice as well, and I think the more publicity there is about bad mothers & hostile ex wives will help blow apart the continuing stereotype that being a "mother" actually makes one a good parent.

5. Spend some quiet time unwinding and reflecting. There are some things you'll just need to accept:
* Bad people exist and they often have children.
* In spite of everything you do, ultimately the child/children will have to decide for themselves what kind of person they want to be, and they may choose to be like the hostile ex. EVERYONE MAKES THEIR OWN DECISIONS ABOUT WHO THEY CHOOSE TO BE AND EVERYONE IS RESPONSIBLE FOR THE PERSON THEY CHOOSE TO BE.
* Just because someone chooses to always see themselves as a "victim" and feel sorry for his or herself, you are under no obligation to do so. My favorite sob story was the one about being "abandoned" by everyone. If you are hateful to others, no one will want to be around you. You're not being "abandonded." You are driving people away by being a mean & hateful person. That's a choice & there are consequences to all choices.
*
Verbally or physically abusive people can be nice, but nice people are never verbally or physically abusive. Don't be misled by temporary niceness.
* You're going to be accused of darn near everything. Unjust accusations can be really overwhelming, but eventually you will get used to them and they may actually start to be sort of funny. Now I'm just waiting for one of us to be accused of the Kennedy assassination, nevermind that neither of us was even born yet.
* Your ex is not miserable because you divorced her. She's miserable because she has chosen to be. You have no obligation or responsibility to her.
* It is not illegal to be a bad parent. I struggled with this one for a long time, but it is not illegal to allow a 7-year-old child to play first-person shooter video games, or to sleep in the same bed with an 8-year-old, or refuse to allow play dates, or to serve only food high in sugar, or to take a child to video game arcades every day, or to have no rules or boundaries, . It might be pretty universally acknowledged to be spectacularly poor parenting, but it isn't illegal and there is nothing you can do about it. You will just have to live with it.
* You will need to decide for yourself how far you are willing to go. Do you want to battle it out no matter what? Is there a point where it might be in the child's best interest (and yours) to bow out? That's a decision only you can make, and no one wins either way. It can feel like a desperate situation, and suicide rates among divorced men are quite high & MANY men have contemplated suicide to get out of this kind of scenario. There are other options and having a child obligates you to pay child support, but it does NOT require you to be miserable.
* This will cost you a lot of money. Our legal system is set up very nicely to allow for legal harassment. Set up a savings account and put money aside every month for legal expenses or whatever else comes up. If you can afford it, put an attorney between you & the bitter ex. We have assumed that we'll both work a year or two past normal retirement to make up for all the expenses of having an attorney, but anything is better than having to deal with her nastiness and spite directly.
* You are responsible for your own happiness. Yes, this is a terrible thing to go through, but it is up to you whether it destroys your life or not. She's racking up legal and medical bills? Make a game of seeing
how long you can go without
buying anything new and HAVE FUN WITH IT. Learn vegetarian cooking to cut down on your grocery bills. When the spite and meanness get overwhelming, have some other divorced friends over and play Bitter Ex Bingo (suggested categories: types of false accusations, scenes at drop offs, hate mail, jealousy--whatever). Do not fixate on the situation, but find a way to cope. A bitter ex can take your money and can temporarily take your children, but kids are smart and they will probably figure things out one day. In the meantime, do not let it control your life.
* Your children and/or your ex wife may destroy any future marriages if you don't learn to cope with them, and they may hope to do so. Most marriages fail & second marriages are even more prone to do so. If you don't have appropriate boundaries with an ex and appropriate rules of behavior for a child, future relationships are probably doomed. Talk with other couples who have survived, go to counseling, commit to making your marriage work. We've been very lucky as working through all of this has actually made our relationship stronger, but it has taken a lot of work and a great deal of humor. We've finally become so immune to her hatefulness that several months ago we spontaneously started celebrating every time a new hassle with her turns up. I don't know if it was the thrill of having an attorney as a buffer or just the realization that we're obviously so happy & making her so jealous that now she's having to go out of her way to create problems, or her obvious desperation to be important to people who couldn't possibly care less about her--whatever it is, we might actually start to look forward to her dramas soon.
*
This too shall pass. Every day, week, month, year that goes by takes you one step closer to being legally free of your hostile ex.
