He is just grumpy and strange all the time these days, no matter what I do.
I noticed he does act funny, but he acts the same way when I try to fuck around with him. As he keeps saying, he is in "a weird headspace these days". And a bit depressed.
He would probably just prefer me not be out in the same bar as him and just stay home so he can have more time with himself.
He needs more flirt from girls for himself. Maybe that will help him feel better.
