Annoyed

My bf seems so annoyed by my presence. He always has a sour look on his face and answers me what as if I annoy him just saying hi. This has been goin on a few weeks on and off now. I'm starting to get pissed because what is his deal. One day he came home and went straight in the bathroom (to poop lo) but didn't say hi or anything I was sitting right on the couch so I texted him "Do you hate comin home?" (To avoid him snapping at me)  He was on his phone playing Nba clips so I know he got the text he never responded. What to do.
