The guy who is dating my mom is a drug addict, is it okay that I don't want her to date him?
Why don't you want a drug addict dating your mom?
Drug addicts are bad.
Drag addicts have issues. It's good to not want your mom to be around people like that.
Her issue is that she doesn't have a job and live off me and my step dad for no reason. She won't even work.
You should speak with her if she is willing to listen, because there's nothing wrong with wanting what's best for your own mother. She has a bad influence around her right now and wanting to get rid of him could be seen as a positive thing and proof that you care.
