My best friend tells me over and over that he's in love with me, but I don't love him that way. I told him this yet he still continues to bug me about it. I get good morning and goodnight texts that are at least a paragraph long. Now I'm falling for someone else and I feel guilty simply because he has the same name as my best friend. I don't know how to tell him that I'm in a relationship now, and that he needs to back off and give me space.
