What do I do to start feeling better about this guy?

Honestly, I think the best thing to do is to try and move on. These things are never easy, wanting so desperatly just to get an ounce out of someone you feel so much for. But its not fair to you if he doesnt feel the same way. No to be cliche, but what doesnt kill you makes you stronger. Take some time to work on you and focus on your own goals and having fun. Its never easy, I'm sorry.
