<human>: For the sake of simplicity (now ex-)boyfriend = Sam, friend = Jim

Before I went out with Sam, Jim had previously made it clear (and by that I mean "told a mutual friend to tell me and hope for the best") that he wanted to be in a relationship with me, and obviously was very hurt when I dated Sam instead, which meant that for the duration of my relationship with Sam (nearly a year) Jim didn't speak to me at all. I recently broke up with Sam, and suddenly Jim's talking to me again, trying to be comforting and all the rest. As much as I appreciate him as a friend (he is a good friend when he's not being arrogant or sulky) I really don't want a relationship with him, which is exactly what I think he'll attempt as soon as he deems me to be suitably over Sam. I really don't want to hurt him again, but then I can't date him just because I don't want to hurt his feelings, and what if I've misinterpreted everything and this time round he really does just want to be friends? Please help me figure out what to do next

Provide a brief overview of the text.
<bot>: Shortly after break-up, old friend is back in the picture and possibly wants more. I don't but I also don't want to hurt him, what do I do?
