When I divorced my kids were fairly little (7 and 4) We weren’t necessarily high conflict, but she had made up her mind - she wanted out, and nothing was going to change that. We had a prenup, but as my kids live with her I pay well above the child support as determined by PA’s guidelines, and in the split I let her have pretty much whatever she demanded. Life’s too short to fight over stuff - but that attitude does make it more expensive.
I’m much, much happier now than I was for most of my marriage. It is not until you are out of it that you see what all you put up with that you shouldn’t. I think my kids are not better off and that they would’ve been better off had we stayed together - they would have had a more balanced upbringing. I have them every weekend (and a number of whole weeks through the year), but it is not the same as being part of their every-day weekday life.
Some things to keep in mind:
Don’t start dating until you’ve been divorced at least a year. Better for you, better for everyone else. You’re not ready beforehand, no matter what you think.
Nothing is fair in a divorce, nor reasonable, Try and minimize the monetary damage. Nobody will recognize it if you are a good guy, and for sure no one will remember it. You will not get validation of any kind.
Long term is more important than current. Meaning - trade current assets for less future costs. You are going to take a hit no matter what, but it’s easier to start over if you don’t have 20 years of payments around your neck.
You need an attorney. However, while you really need an attorney, you also need to make sure they don’t clean you out. They can get expensive in a hurry. Never be in a meeting with multiple attorneys - ask whichever one who doesn’t have the answer to leave - if they both have the answer ask why it takes two. It makes no sense to spend 30 grand in attorney fees to maybe save 30 grand in the split. Frankly, it doesn’t make sense to me to spend 30 grand even to save a possible 50 in the split. This doesn’t mean that you don’t start by asking for this - it means don’t dig your heels in out of “principle”. If it did indeed go to court, you hung on too long - ideally you figure out the money in conference/mediation.
Fight for as much custody as you can get. Not all time is the same - the details of the time are as important as the amount. Especially when they’re little, see them as frequently as possible. If you can’t agree to the custody, it’s worth fighting it out in court. Time with your kids is the only thing you can never make more of. I don’t begrudge any cent I spent on court to get as much custody as I got.
You will hear accusations that can be very upsetting because they are so unfair. You have to let that go. Again, there is no validation, no recognition of the value you add. Let it go. The divorce is about money and custody. Not right and wrong.
Just because my life got better after divorce doesn’t necessarily mean yours will, unfortunately. I fought hard to not divorce - counseling, willing to relocate to placate my spouse at the cost of my career, and other things I choose not to disclose. But she would not budge. If not for that, I would feel a lot more guilt, especially regarding my kids.
