What do you do if your parents don't like your friend?

I know what you are going through, and I also know it hurts your feelings when you mom says's ," I don't trust her," or "how can you be friends with someone who treats you like that?" But, think to yourself how does it make you feel when this person ditches you or does whatever. All I can say is think about why is your friend doing it; low self esteem, bad friends (not you), or even (I know it sucks) is a bad friend. I have stuck by my friend and it is hard, but I love her as a sister, but if it comes to much of a wedge between my mom and me, I will stick with my mom because friends can be replaced. MOTHERS CAN'T.
