Is it just me??

Hey guys! I don’t usually post on here, but I need some insight. I’ve been feeling like my boyfriend of 4 years has become a little distant. For example I always have to repeat myself to him because he’s on the phone or watching tv. If I do the same thing or genuinely don’t hear him, it becomes a problem. I try to confront him about it but he always finds a way to talk himself out of the conversation and the cycle starts all over again. A friend of mine says that he’s just being a guy, but he knows that I’m a talker and that I like to be heard, so why the change? Please help! Am I overreacting?
