But I personally know a BM that does :) My DH's ex hated all the other women my DH dated before we met. She hated them all, threatened them & one made several police reports against BM. She chased them all away. I was the only one that stayed, married DH & had to get a RO against her. LOL so yes, I think my BM in my life hates that her exH had sex after her :)
I had sex after divorce, and he wasnt supposed to? I hated him that he has sex with her while we were married though.
I think reducing a BM hate for SM to she hates that her ex is having sex with someone else is simplistic and stupid. An easy answer. Sort of false pride.
I tried really hard to figure out why she hates me. Where i got to was a broke up her post divorce family. She had it all worked out, neither of them had serious significant others, she still called him on a daily basis, and she didnt have to have sex with him. It was perfect. I fucked it up.
What a silly idea that mothers hate the women their ex is having sex with.
