<human>: So one night 3 months ago my husband(25)  ,of almost 4 years and parter of 7 years in total, says he wants a divorce. And then proceeds to sleep around with a girl a few days later while we are still living  in the same house and the same bed . 

I end up moving out , and we try to remain friends. He tells me he won't do anything again until the divorce is final. So we start sleeping together again. Then a few weeks later he sleeps with someone else. This time I'm hurt, so I had originally agreed to leave the furniture in our house until it sold, but I took everything we agreed to divide and swore I would never talk to him again. He begged and pleaded to please give him my friendship and that he was sorry.

 So I started talking to him again. And now we are back to kind of having sex every time we see each other but I feel used. And when I tell him he says we don't have to have sex to be friends, but I'm not sure I want to be his friend at all. He is still seeing these girls and I just feel nasty at the end of it. And so I tell him again I don't think it's a good idea to stay friends but he begs me to please remain a part of his life. I'm confused. Why would he ask me for a divorce and not file after all this time. And what is the point of being his friend? I'm heartbroken and he doesn't understand remaining friends is hindering my ability to move on.
Of course I still love him and I am willing to still work on our marriage , but I'm not willing to work on a friendship.
