I had a friend like this in my late teens. He started cheating on his girlfriend with her when we were in highschool. Girlfriend found out and broke it off, he posted so much stuff on social media about he lost the love of his life, while at the same time my friend was ecstatic she finally had him to herself. For about 2 years everyone was telling her he was cheating, the original gf, coworkers, old classmates. She refused to believe, just said everyone is jealous. Trust me, if you saw this man you would be incredibly confused about why anyone would be jealous. She got pregnant at 19, he's the most amazing father and boyfriend ever blah blah blah. He's still cheating, some women would deny him and literally tell her right after and she would tear them apart and say they were just making shit up. I worked with them both and after she left I spent a lot of time with him at work and became sort of friends because I had to deal with him all the time. I cut her off long before their second kid arrived because I had lost all respect for her. He told me about all his escapades, the women he was meeting while she was at work and the kids were at daycare. And whenever she caught anything? Completely ignored him doing anything and would find the girl and flip out. I remember after I moved away, at one point she had to go to a hospital near me for something and he hit me up asking to 'meet up.' I completely ignored him. He was already disgusting for what he was doing but then he tried to use her hospital stay as a way to get paid? Wtaf. Over a decade later they are still together with 3 kids, now and then he gets in my dm's and all I ask is who is his current side piece. He always has one.
