2 sayings come to mind.... It's cheaper to keep her, and you know why divorces cost so much? Cuz they're worth it!
All joking aside, it's rough. My ex and I probably could have done our divorce on our own, but it got to a point where I couldn't belive a word she said, so I hired a lawyer. She was very good, I was overall happy with the end result. If you have kids, there are advocacy groups for father's rights, sometimes offering free help. Also if you have kids, keep a notebook or journal and write down EVERYTHING!!!! I had a calendar that i wrote the dates and times I picked up my kids, what we did, and kept every receipt (clothes, food, meds, movies, etc.). We actually had a settlement conference outside of court with just us and our atty's to hash out all the details. Make sure you read everything thouroghly before signing. From my own experience and what I've heard rom frineds who went through a divorce, and had kids, it seems like fathers are getting more fairness from the courts than previous generations. It's best to be as civil as possible to each other, and no matter what teh soon to be ex says about what you can and can't do with your kids, your rights do not change until you have a finalized divorce back from the courts. I'm not tring to sound mean, but you learn a lot when you go through this.
Good luck!
