Thank you for replying. We had a camping trip booked over the weekend which I decided to go. I wanted to give him the space and time just between us to be able to tell me about his problems which he did. He opened up a lot and was the most honest I've ever known him to be. I really didn't want to make it about myself, I just wanted to offer him support, but unfortunately I realise that was asking too much of myself. I now feel more confused than I ever did. We have an amazing dynamic when we're together, we just bounce off each other and I found that whenever we weren't thinking about the problem we just naturally ended up like this. To the point where at times I found myself thinking I could stay with him and help with conquer this. It's only now I'm home, and back to reality, I'm starting to wonder whether or not I can. I don't want him to feel messed about either. I love him very much and when it's amazing it is amazing. But has it only been amazing because he's been happy getting what he really needed elsewhere? If he finishes doing that will I actually be enough? Can he stop doing it? Is it going to be a year down the line I find out that he's been texting girls all over again? I'm worried I have no self respect and I'm a mug for staying with him. I'm worried that what he has isn't quite a full blown sexual addiction, rather he is just highly sexualised, a flirt and a cheat. I'm angry if he feels like he can say "it's not my fault" which he does, to a certain extent, believe. I have overcome an eating disorder, for the most part, but still suffer with low self esteem. I do understand how hard it is to actually talk about an embarrassing problem. However, with my low self esteem now comes me wondering what's wrong with myself. Is this the most unhealthy relationship ever? Can it actually survive? He says he will do everything it takes to prove he can stop this and that he wants to be with me. And I want to believe him so much, but is that to my own detriment? Sorry for the most confusing thread and all the questions, but if anyone could reply with any type of advice please do. Is there anyone out there in a similar situation that stayed with their partner and did it work?
