How do I help my friend?

[neji]

My friend is in a relationship with a guy. he has forced her to block all her friends including me on Facebook and Twitter and he also has forbidden her to talk to any of her friends. She is the type of person who is kind and doesn't like to hurt people but she is easily hurt. I am friends with her boyfriends cousin and he tells me that he treats her like crap and I have also seen this happen. I think he's using her kindness to control her. What should I do to help her I've tried to talk to her about it but each chance I get he pulls her away or she's to scared to talk to me. So far there has been no violence in their relationship thankfully. What should I do?

Just tell it straight to her in front of her boyfriend, text her, call her, ect.
If you are truly want her to be happy, want to help her then you should do that.
