What's with this guy lately?

He sounds a bit immature, but he is definantly missing you otherwise why is he seeking out all of your friends. I think that he just doesnt know how to express how he is feeling for you without apologizing to you for the past harm he has done. What you should do is ignore him entirely, eventually hell get tired and just pull you aside and tell you how he feels if not then im sorry honey he might not be worth it.
