I met a guy through mutual friends, we hit it off from the start. He took me out, he was always avaliable, made plans to see me, never once cancelled. We sleep together for the first time and he is now suddenly unavailable. Two times I have suggested we meet and he declined one and cancelled the other. I've been used haven't I? Do I just stop all contact with him now? I've tried to give him the benefit of doubt but he has never done this before we slept together.
