i am a regular but have nc from this because its such a recognisable situation to anyone who know me irl. This is likely to be long so please bear with me...
A couple of years ago when I was 21 I met a guy online for casual sex, he was in his late 40s so significantly older than me but we got on well. I knew he was married from the start but his wife was aware and also seeing other people.
it worked really well for all of us but it became obvious that their marriage was not a strong one. He'd had an affair years before and she hadn't forgiven him. Instead she told him she wanted to see other men and he agreed to an open marriage.
After a few months she became jealous and asked us to stop because she was worried it was becoming more than sex, which we did but neither of us were interested in a relationship anyway. Then somehow it got around to trying a threesome which I was happy to to do because I've had relationships before and we all got on well.
The one thing that put me off a bit was that for her it was sheer curiosity and she said she wasn't interested in kissing or anything affectionate. I did it anyway. Part way through the first time she kissed me and then asked me to spend the night with both of them.
I don't know how but I completely fell for her and it very quickly became this all consuming thing where we were constantly talking or texting. Sex had very little to do with it at this point I just wanted to spend time with her. Her DH knew we were meeting separately but I wasn't seeing him except when she was there.
I asked her to leave him and stay with me, but she said no because she just couldn't deal with people knowing she was in a relationship with a woman as young as i am and when she got married it was for life. So we carried on as we were for 6 months and then they moved abroad and have been back for one holiday since.
This has been going on for 2.5 years, since she left we have spoken at least by text everyday. The marriage is a lot stronger than it was and is now monogamous and they seem happier. The fact that she and i want very different things has caused some awful rows but I just can't seem to give it up. I KNOW this is a dead end. I told her so 2 days ago and we were both upset, but I've done this before and then I miss her so much I go back and try to be friends. I just can't have a relationship with anyone else because its not her and I'd rather be single. What I need is a way to stay determined not to contact her, whatever happens.
I can't see the wood for the trees to be honest so an outside perspective would be much appreciated
