A guy I was sleeping with for a few months recently found out that I had been sleeping with someone else when we first got together. Now he's told me that he just wants to be friends but he still responds to my text messages and phone calls (which aren't terribly frequent - usually once or twice a week I'll text him to say) then stops responding as soon as I mention getting together. I did tell him that I really like him and he told me he doesn't want a relationship but we agreed to keep seeing each other. However, he acts completely differently toward me now, he used to call me all the time and want to hang out a lot and now he never says anything when I mention getting together. I know he was upset about me hooking up with this other guy - even though we never talked about dating exclusively. I really like him, but don't know if I should just leave him alone, or if he just needs time to learn to trust me. I have stopped seeing other guys, mostly because I don't like them as much as I like him. We are both in our early twenties, so I'm not looking to get married, but I feel really comfortable around him and we always have a great time. Please advise.
