Advice needed please

My partner, I and my son all went to my dad’s house today and hung out. We took pizza and got there around 3 pm.

Well every single time we go to my dad’s and I take my boyfriend he decides to fall asleep every single time we’re there. He’s done this for a long time now and I’m getting sick of it. It’s rude as hell. He knows I think it’s rude but he continues doing it.

Also every single time we come home he’s on his game for hours and doesn’t care. It’s actually too much tbh with you. If I went to his families house and slept he would call me rude, ect.

It’s nice for him to sleep and not socialize at my dad’s but he can for himself, weird right? Unless someone has another perspective I’d love to hear it. I’m thinking about breaking up with him over this because I’ve asked him to stop sleeping when we are places and no he doesn’t have narcolepsy. Also it was his idea to even go to my dads I really don’t understand.

My boyfriend is my sons dad too btw
