Should i get back with him ?

this is confusing and doesnt really make a lot of sense... are you saying that your boyfriend broke up with you because he had an argument with your friend? that doesnt make sense why would any normal person do that? you're probably better off without him. and your friend hannah sounds a bit stupid too, what sort of friend acts like that? who cares what she thinks about him too, I wouldn't if I was you. if you want to be with him then its got nothing to do with her.
