confused

I know my boyfriend isn't going to leave me but at the same time I feel like he doesn't want to be with me, every time he gets home from work he wants to chill Alone and play his game then after 2-4 hours he gets off gets something to eat and watches YouTube videos on his iPad, he thinks just because we live together we don't need to spend time together cuz he said we got to the point of our relationship where we can be comfortable, we only get to watch a movie together and lay in bed talking but he says I always talk about the same thing over and over again, idk what to talk about with him anymore..... I'm not that good with conversation or making it interesting..... I feel like we are drifting apart well I feel like he is but he says he has to get yo super early go to work deal with that and he has alot going on, I don't understand why guys are wanting to be alone when this happens.... I thought he'd just vent to me and us talk... he's not very talkative..... I have these thoughts in my head like maybe the reason why he's acting like this is because he doesn't love me anymore...... but idk
