I have a real tough situation. My girlfriend of 5 years whom I have 2 kids with recently left me. It came to light that she had been cheating on me. Our relationship had gone pretty downhill and she was unhappy. I hurt her emotionally a lot, and she turned to this guy. They are having a lot of BDSM sex. It's something she's expressed she wanted to do with me but, I've never felt comfortable with her sexually because years ago she left me and was with another guy, doing the same BDSM stuff. I've kind of always felt like I'd never meet her expectations there. We never talked about it because I've been kind of closed off in many ways.
Anyway, she is so blatantly distracted at this point. She's always on her phone. When we're together with the kids she's texting (I assume to the guy). She doesn't seem at all interested in giving this up in any way. It's painful to see. This guy had a fiance' who he apparently still lives with and does the same stuff with her. He's said some awful things about my ex, to both his fiance and to me. He talks about her like a piece of meat. It disgusts me. Obviously she's left me because she was unhappy but how can this situation be any better. I don't think there's anything between them other than this, but the fact remains that she's doing this.
When it came to light that she was cheating, she called it off to deal with the aftermath. The guy freaked out, she seemed to be very much done with him because of how he was unable to let it go. But two weeks later after things calmed down she was back to it. To see the bruises and marks some other guy is leaving on her is unbearable.
I'm not sure how to cope. I'm seeing a therapist on Monday but it seems so far from now. I just wish she'd come back to me and work things out and then we could go from there. I hate seeing her go this route. She says she has things to deal with but it seems to me like this is just a way to be single and have the sex she's been wanting to have. She's alienating everybody. She's buried in her phone constantly. She's lying about where she is and what she's doing to me, her family, her friends. I want her to see a therapist but she refuses. She thinks she's got things under control but at this point I'm not sure. I'm afraid she may end up pregnant, or hurt, by this guy. What can I do?
