Drifting apart

Things are NOT the same anymore and it's slowly tearing me down. I don't know what to do with myself. You were my best friend. I feel like I can't even tell you anything anymore without you getting mad or defensive. Your moving date gets closer and closer and all that keeps going through my mind is the fact that we will be even more distant than we are now. My heart is literally breaking and I dont know if it can be put back together if I dont have you. I've been trying my best to do absolutely anything and everything to be with you again and I just keep getting shut down! I think I've come to the conclusion to just let things be and to not talk to you anymore. It's too hard to just "be friends"...it's not possible...at least not for me. Every time we hang out as "friends" it just brings more feelings and I just set myself up for heartbreak. I hate feeling this way. This is the worst feeling ever. Something's gotta change.
