Boyfriend calls my mom names, what to do?

My mom is sometimes strict, and only takes me to my boyfriend's house when she wants to.. I always stay until late at night, and sometimes, if I'm with him for a long time the night before, she won't take me over the next day. Zack, my boyfriend, will call my mother dumb, and stupid. Do you think this is wrong? what should I do?

She's probably just worried about you, don't let him call your mother dumb. Especially if you didn't say it first. She doesn't want you getting stds and knocked up. Explain that to him. Would you rather her not care about you at all? Or not drive you over there at all? He should respect you and your family. Your mother birthed, raised, fed and clothed you at least, so you owe it to her to stick up for her when people are talking bad about her.
