I recently started hanging out with a guy I know from a group of mutual friends (I'm a female). It started out with him thinking he may want to date me (I didn't know about this until later, I just wanted to be friends). Then he changed his mind and decided we were better off as friends. We hung out and texted for the next couple months, but since April all I get when I ask him to hang out is "I'm busy". It went from details about what he was doing to just I'm busy to not answering at all. He posted a very nice birthday wish to my Facebook page a few weeks ago and did answer a text I sent that was just asking a question and not asking him to hang out, so he is still talking to me I guess, he just doesn't want to see me. I don't know if I've done something or if maybe he thinks I like him more than a friend now or what. I've been told by a couple friends to give him space, but since I don't know what the problem is, I wonder how more time is going to change anything. I'm very impatient as well and just want an answer so I can either move on or try and fix the friendship. I thought about sending an email asking what happened. Is this a good idea or should I just keep giving him more space? This really is killing me, especially since we have mutual friends. I'm avoiding a dinner tonight that he's going to because I know it will be awkward for me.
