When you can't beat em, join em.

just imagine if OP would have called the cops..there would be another FML coming from the OP's flatmates...

He and I both came from a bad back rounds. He turned some what out like his father. I've seen him him it women but never like beat them. We're as I turned out like my step dad.

You are an awesome person. Thank you for caring about her safety. Even though it was an awkward situation, it's good for her to know someone is looking out for her especially if her boyfriend has violent tendencies. We need more people like you in this world.

No clue what you're trying to say

After a lot of bad grammar translation: OP and his flatmate both have abusive fathers. His flatmate, though not as bad as his father, has anger issues. He has, in the past, hit women although never truly injured them (side note: never okay to hit people you are in a relationship with, whether or not it qualifies as "beating"). OP, in contrast, turned out more like his step-father in temperament. Poor sentence composition aside, fantastic for you that you would step in and do something about that situation. Really awesome and brave of you.

If he's hit any previous girlfriends before you should've beat his ass anyway.

I'd rather barge in and be wrong than not go in and be right. Good on you for trying to stand up for her, OP.

#78 thanks for explaining in detail...

did you at least high-five him?
