Thanks for the replies, guys. I do indeed think alexandra may be on to something with the idea that he just doesn't value the relationship as much as me. I mean, it's quite obvious, but I gues i need to find out if it's because he's just not looking for something deeper with anyone, or if it's because he just doesn't like me that much.

I do indeed think the next step will be talking to someone about this, and I think I know just the friend who would be good for that. Very understanding and open-minded guy.

Thanks again, I will keep you posted. I've waited far too long to get this all sorted out.
