Not saying she isn’t a big part of the problem, but you shouldn’t poach a woman from a WLW relationship, who’s only ever been involved with women, and then get upset when she continues to love women. This is why I would advise him, being that he is 38 now, to not mess with women who are a lot younger and often don’t have that figured out. Especially since she was apparently only 18 when they got together…18 year olds don’t know shit, and the sink cost fallacy sets in before they figure it out. So many times I see people of both genders staying in relationships out of comfort or because they don’t want to rock the boat. I don’t think he is a monster at all but there could be an argument made for “idiot.”
