got assaulted by boyfriend friends while he was cheering them...

[Oliver]

I've said it before but no one listened- the story of my life- and so I'll say it again. No one should accuse another poster of being a troll on the basis of one post. The civilised way in which to handle the situation, if you suspect that a new poster is indeed a troll, is to ignore the post.
In this particular case, a guy, obviously distressed and much younger than most of us, has asked for advice. Even the most self-confident of troll-hunters must surely accept that there is a possibility that it is a genuine cry for help. One chance in ten would, in my estimation, be enough to take the post seriously.... or ignore it. Life is too short to get our knickers in a twist over whether a particular post is genuine or not.

Accordingly, myadvice- as many others have suggested- is to end the relationship.
