For a few days now my good friend has acted like an *** hole to me. Should I confront him about it or see if it continues?
There's a reason behind it, don't address it just act the same way back and if he questions it tell him your just treating him the way he's treating you.
I think you should confront him about it. Maybe he is upset because of something you did or he is in trouble. Find an appropriate time and ask him why he is acting strangely.
