What is every possible thing you can do to a woman who cheats on you? What if you don't have the abs or wit to **** another woman? Both in the scenario where you have kids and the scenario where you don't?
You need to split. But, there are some things to consider first:
#1 Don't get married or get married again. There's simply no reason to. Fairy tales only happen in the land of Disney. Not trying to be negative, just the 100% truth.
#2 Stash your money, assets, whatever, but get everything lined up financially first so when she tries so take half or more and make you pay "maintenance" the bulk of your cash is gone. Many ways to do this legally.
#3 Try to be as amicable as possible. You'll have to bite your tongue a lot. Family courts are WAY in favor of the woman so purposely tying to be an assh*le will only come back at you 10-fold.
#4 Take a break from women and work on you; career, body, money, mental health, whatever.
If you're not getting better, you're getting worse. There is NO in-between. Do the hard work.
Good luck.
