Pressured into sex, opinions please?

This is on behalf of my 14 year old friend who I'm worried about. She promised to have sex with a 16yr old guy friend of hers and would flirt with him constantly and said she would have sex with him at some point when she was over at his. This went on for a few months. She finally agreed to definately having sex with him. They were sitting on his bed, when she said she didn't want to anymore. He played with her mind saying things like 'you can't f*** with me like that' etc etc, then after 10 minutes of getting angry, he walked out into another room. She spent the next 5 minutes crying on the phone to me, I told her to leave, but she then walked out and agreed to do it. She says the only reason she did it was because she knew if she didn't she would lose him as a close friend and she didn't want to lose him. She lost her virginity to him and has not stopped stressing about it since. What do you think of the situation? What worries me the most is when she said 'I've already done it once now, I may aswell keep doing it or I'll lose him.' Advice, opinions, anything please!
