I can relate to this poor guy. I once met a girl at a beutiful girl at a party.
Ten years later I woke up and she had my house and 75% of my money and making me pay her to see my kids.
I’d crawl through broken glass and pay whatever it took to see my kid(s) and while I may not be happy about it or endeared towards the other parent, I’d do whatever it took to be a part of my child’s life.
It’s funny how often I see men on this forum complaining about how the ex wife took them - but seldom do they explain how they chose their ex wife and maybe (maybe not) but, if there had been better choices than just looks at a party, the ending might be different later.
