The girl I have been mooning after for the last 3 months finally told me that she does not love or want me like that, but she does sincerely want to be friends. She said she didn't want to hurt me, but honestly it was a load off my chest. However, I put in a lot of energy over the lat 3 months that could have been spend elsewhere.
So, ladies, if you have a fella who is all about you but you're just not that into him, tell him. Tell him in a clear, unambiguous way. He may not like it, but he'll eventually appreciate it.
