distant boyfriend

Okay I need some advice. My boyfriend has been acting so distant this entire week and just weird this entire month actually. I've been freaking out thinking maybe I did something? But he gets mad when I ask what's wrong. He pulls the "nothing's wrong stop asking" card. I talked to his mom today and she said he's been super weird this entire month to everyone at his house as well and I'm starting to think he's still hurt over his big blow out he had earlier this month with his dad. Which is fine and I'd understand, but when he gets upset he just puts a wall up and pushes me out and it drives me crazy. I can't help but to feel like it's me he's mad at. I didn't do anything, I don't feel like I should be pushed away for it. I just want to help. I've tried telling him that as well which only went into him getting mad. Anyone have any advice for me?
