I've been on/off close mates with this dude from Year 7-11 and now that I'm in sixth form we don't really chat as much because we're in different lessons and I spend more time doing my work than using online messenger (we used it a lot back in Year 7-11). So I've got a new group of friends, and a girl I've got my eye on, but I just sense some sort of grudge or resentfulness whenever I talk to him. I don't really understand what I've done.
I understand he's a sensitive person, but I don't know how to act around him when I run into him at college. Usually I just ask how he's been etc and we have a laugh but on IM today and yesterday I initiated a conversation with him and he gave a short answer and immediately signed offline. I know he's doing it on purpose and tbh I think it's just childish but I don't really know what to say to him. I cbb confronting him and saying "Look, it's not my fault that I don't hang around with you guys anymore.." because things are good right now, so any ideas on how to act around someone like this?
I spend less time on IM because I really don't see the point in it anymore, back from Year 7-11 it was cool doing all-nighters and such on it, but now it's just a bit "waste of time". But I just started talking to the girl I like over it and she seems a bit more open over it and we've had a good conversation through it, but this dude is being immature so I cbb using it just so I can concentrate on my goals (girl, education) and not some resentful friend. Actually, what's his problem, does anyone know? It's bugging me now.
