One thing that bothers me is when he comes up real close and leans his face into mine and stares me down on purpose. Is he trying to jokingly intimidate me or what? I just try to get him away by telling him to stop and messing his hair up to shoo him away. We're kinda close but we grew apart since he dated my best friend.

Any ideas to why a guy would do this?
And he always asks me to sit on his lap. What is up with that? He has a girlfriend.
