I understand that in a relationship, there is always a path filled with rocky road with bumps here and there. The problem that i have seen in my friends relationship with her boyfriend is that the fights that they are having is slowly grinding her away the very person that she is. I just don't know how to bring her the truth that its starting to eat away at the very person that I've gotten to know and love all my life.

Some of the ways I her being in a abusive relationship is that :
1. She feels helpless and hopeless whenever he begins to speak to her, even if that is by word or texting. (i havne't had one outing with her in which he hasn't called or text her about something and not go into a depressed state)
2. She feel like you are always walking on eggshells and afraid of angering her partner.
3. Her partner humiliates her. (has made vulgur statements that they would have sex any chance possible, without really allowing her the choice of having it)
4. Her partner makes fun of her regularly (always tells her what she does wrong or is wrong with her)
5 Her partner is extremely jealous. (Any guy that she hangs out has to be specially seen / has to know him)
6. Her partner doesn't allow her to see friends or family members (I even have trouble seeing her due to him )

I want to do something but i've realized that she doesn't realize that she is in such a relationship and that it seems to her that everything is going perfect.

I'm truly scared when I heard from her that he had proposed to her and that she said yes (And to make things better, he is 17 and she is 19). They haven't announced it to their parents but she has informed me that they will at the end of the summer, which I know will destroy her relationship with her family.

Please, if anyone has advice, i would truly appreciate it. I just want to make her realize without destroying our own relationship.
