First story: he been waiting to do that, he was inconsiderate after you lost the baby which would he a huge red flag to divorce..you letting him sleep with other ladies showed how numb you were he didn't care ...so stay with the man that makes you feel alive again especially if it's genuine
2nd story : you are a terrible person. ‘There was nothing I could do about it’ ya you could stop seeing her, ‘I’m an evil man’ heck ya you are. I fell so bad for the girlfriend. The sister is also bad but not as bad as you .
You cant really control love, but you can control yourself. Its 100% his fault. He fell in love with her sister instead, which is ok, but what isnt ok is making out with her. Thats still considered cheating. And if he has the balls to do it while her friends are there, he has the balls to tell her over text.
I hope the man in the 2nd story stays single forever that was so mean and the sister why that's ur own blood why would u break ur sisters heart for a man who would probably cheat on u
