Alright, so my brother and his girlfriend constantly get in very heated arguments, where his girl says he's useless and will never be a good man. My brother is always saying he is capable and will change. It seems as if the girl wants to be the dominant one in the relationship, and she always says that he will 'never find another girl', and 'this relationship is over--I'm breking up with you!'--PS they never actually permanantely break up. I've been in two real relationships-none lasting longer than a month though...so, is the above situation standard?
