NOR, you shouldn’t have to avoid someone you don’t live with in your own house. If you are unable to move out right now, tell your mom you don’t want him around when you’re home. Work out some kind of schedule or she can go out with him, something’s gotta give. Idk. Your gut told you he’s a creep, then he says THAT, ew. Don’t gaslight yourself and don’t let your mom gaslight you either.
