My ex husband and I were married 7 years and have two small children. As soon as we broke up, we started sleeping with each other again. I had feelings of how that we would get back together, but he's a sociopath and is incapable of relationships, so it just became pure sex for both of us.
Flash forward several months later: he's living in another state with his girlfriend. He sees the kids every two weeks and we still sleep together when he visits. There's no feelings on either side - we just enjoy sleeping together and, not bragging here, I'm pretty good in bed. I'm sure the big reason he sleeps with me is b/c the new girlfriend is boring in bed.
Even though he's talking if marrying her and having kids, he continues to sleep with me. I'm aware of what I'm doing, I don't regret it because there's a strong sexual attraction there. I'm actually wondering why he would cheat on her - I could never cheat on someone I really love. If he's making these big plans with her, why sleep with the ex?
