My ex and I separated in October of 23 and finalized the divorce late last year. During that time we both had a mutual friend that we both spoke to early in the separation. I asked for advice for an attorney because he had been through a bad split. His words then were "how bad do you want to fuck her over" and I had said not at all, I just want to get divorced lol. Fast forward a few months and that guy began bringing his kid over to hang with my ex and my kids. I had a weird suspicion the whole time but turns out that they are in fact dating. It just feels fucked, like of all the people I now have lost a friend and have to now hear about this fuck from my kids. I feel like just drowning in a bottle but I know that won't do shit. No worries if there aren't responses, I'm just fucking ranting at this point.
