I need someone gay/bi for my problem.. its quite long but interesting, thanks?

I don't see the big deal in adding him, you go to the same church, you have mutual friends, it shouldn't be awkward for you to add him as a friend. It would only be weird if you found this person out of no where. The obsession that you have with him however is a little odd, facebook isn't real life so don't take things that happen on it so seriously.
