Relationship help

My boyfriend and I have been together for almost 2 years we have a little boy due on August 14th well about a week ago we got back together after being broke up for about 2 weeks. He works all day Monday-Friday and sometimes Saturday so I hardly see him he just eats and goes to sleep. Even on his days off he smokes weed, eats and sleeps. I don’t smoke obviously cause I’m pregnant so I don’t get to do that stuff with him so we don’t really do anything together anymore I constantly tell him I’m tired of him always wanting to smoke and sleep. Am I wrong for being bothered by this? I understand him sleeping after work that’s fine but on his days off he doesn’t want to do anything. We are about to have a kid here so it’s just hard. Any advice?
