My friend wants to be with me and I just feel so guilty about it.

I met him through a mutual friend about a year ago or so. When I met him I was single. About 6 months ago I got back together with my ex, who I have 2 children with.

I always knew that my friend was interested in me. In fact the reason we began talking is because he saw me talking to our mutual friend and found me attractive and wanted to get to know me I guess. I never really gave him a chance because I lived pretty far from him at the time. Not to mention I just wasn't ready to be in another relationship.

Recently he said something to me along the lines of wanting to make me happy and be there for me and my kids. I don't know, it just broke my heart. He's so sweet and genuinely likes me a lot. I don't even know why.
