Every time I go out with my boyfriend my 18 year old gets really upset with me. If me and my boyfriend get into argument. Instead ad of her asking if I'm okay she talks down to me telling me I'm stupid and that's why my man doesn'twant me. She also tells me hhe's not my boyfriend that he's a trick. And when I come back from seeing him she attacks me verbally and doesn't really wanna talk to me. I don't understand what's her problem. Can anyone help me? Also my boyfriend has did so many nice things for me. Like buy me my favorite cake on mother's day, bought me a car, and we do everything together. So I'm very confused in why she feels he doesn't want me. When he and I are always together. Please help me I ddon't understand her behavior. I can't share anything nice about him to her. Without her getting upset or just plain out telling me she doesn't want to hear it
