Is my boyfriend losing interest in me?

My boyfriend works long hours as a manager of one of his fathers many stores. When he comes home from work I am always so excited to see him! We usually hangout in our room, watch tv, eat some dinner & play a game or two together. Lately he has been coming home and watching tv with me like normal, but doesn't really talk to me, I want to discuss our days, see how work went, snuggle with him. He will just lay there and ignore me and have his face buried in the television screen. He hasn't been as affectionate to me either. I don't know if hes either losing interest in me, stressed from work, or i am just over thinking things.
