Venting

I’m not sure if I’m overreacting or what but something has to give! Recently I have realized my partner doesn’t want to spend time with me. We will just be watching one of our shows and pauses it and says “we’ll im bored” want to go out to the garage and work on your car? I said no not really…so he goes by himself. He works all day and doesn’t want to just chill with me. Idky we have to be doing something 24-7 what’s wrong with chillin? We have a 4 month old so that’s where all my attention goes. I confront him about it and he says it’s not about me and he man main point is I’m trying to make I’ve told this dude it’s not working it’s not working you don’t like me like that. He doesn’t, and he also doesn’t believe me. Which I’m getting pretty fed up with smh
