Do you think this is a fair situation?

Well, I’m seeing this boy. He’s great. My problem is, is that his mother doesn’t like me. (No surprise there.) She searched for my Facebook and she found me. She found a picture of me smokin’ a cigarette, she thought it was a joint. Yeah, I admit that is immature but, this is my life. So, she goes on to tell my boyfriend, ‘Cut off all ties with her.’ She’s never met me. She also tells him he’s a failure and blames me. I’ve known him for a few years but I’ve only recently started talkin’ to him. Whenever we hang out, I make sure he gets home at a decent hour, he doesn’t smoke or drink with me and all around, I think I’m being responsible. I’m a good person, I go to school, I don’t do drugs and I have respect for others. I let him borrow my iPod so he could text message me. She takes it away from him. Can she really be doing all of this, am I getting treated fairly? I know she wants the best for her kid but, I think she’s being immature.
