Bear with me, I am hopeless at reading people and situations, so might be overthinking things.
I get on with most colleagues in the dept I work in. They are very friendly, like a big happy family so to speak, which is lovely as I normally find it hard to get on with people. ( I have Asperger traits).
Anyway, one of my male colleagues seems to be behaving a little strange. When he talks to me, he barely looks at me.
If I ask him for help on something, he flies through what he needs to help me with very quickly, like he can't get away from me quick enough.
If we are alone in the same room, he laughs nervously or giggles, and I feel a sort of atmosphere, and its a very quick concersation always regarding work. But when other people are in the room, I get short sharp conversations from him, or he acts like I am not there, or only speaks to me if there is somebody else involved in the conversation.
Plus also, he has moved out of the dept, although I see him around during the day. I feel like I've done/said something wrong.
Should I ask him if I have? I'm scared if I do ask, that it might not be anything personal I've done/said, and looks like I'm 'finding' problems if none there, plus he might have been moved out of the dept by management and not him voluntarily, iyswim.
