As a family lawyer here is what happens everyday.
Either you bend over and take it by letting her have most everything including a high child support or you do battle in court.
If you do battle in court, you will likely lose. She will bring every skeleton from your closet and show you to be either a drunk, abuser, pervert, or whatever. You will end up losing 3/4 of your friends who will side with your wife. You will likely rarely see your kids, or they will used as ranson to get higher child support or maintenance. Yes, divorce is fun, but the only ones who profit are the attorneys. Sounds like you will be in for about $50,000, at least for round one. Most attorneys in family court want to see your wallet before we will take on a contested divorce. We don't want to get stuck holding the bill. You see, whether you lose or win, we always win! Choose an attorney carefully, it's hard to choose which are terrible and who are truly terrible.
