<human>: Can you condense the text into three sentences or less?

I'm recently single and started seeing this guy as a rebound kind of thing, we have been friends for about five years so things went kind quickly and we slept together a few times.  Anyway he went overseas for 3 months right after we got together (bad timing) and we barely spoke while he was gone.  Now that I am over my break up and can see the situation with a clear mind, I realise I can't see a future with this guy, I'm not that attracted to him and he's really not someone I would normally date, so I'm discounting this situation to a rebound thing. However, he's just returned from this trip and expects us to pick up where we left off.  In a way I want to because, honestly, I'm a bit lonely - but that's just it. Not because I want a future with him or anything like that, I'm really just a bit lonely. 

If I choose not to date him, how should I tell him?
<bot>: Not sure if I should date this guy, and if I choose not to, how do I break it to him?
