Venting

So my boyfriends mom lets her son (14) smoke like pot and black n milds. Inside the house! In my boyfriends room while he is away at work! Mind you I live with my parents and I come over here to see my boyfriends mom and my boyfriend when he is home. I’m 28 weeks pregnant. I’m about to tell my boyfriends mom that her grandchild isn’t aloud over here when she is born. My boyfriend will be mad at me for saying that but if you can’t smoke outside you can’t see my baby.
