Thanks to all for the replies.

Yes, I think it's better to close with that man. I don't want to hurt anybody (particularly, his wife, who has no fault) and I don't want to suffer more.

Oh and I didn't tell him I simply wanted to be his friend, I took this for granted, then things changed but this is not I really want, I see this is not an healthy relationship.

I'll keep you upated.

thanks for the hugs, unaluna
