wow thats terrible. you know the first thing you should have done is to investigate the mood before approaching a drunk. its one of the things i learned about handling people at sainsbury...but pretty helpful! make sure that he doesnt have any sharp objects. you said he had previous history of abuse, so you should pretty much know what to expect out of someone in that state. i can see that you love him, thats why you made up with him. it can happen to anyone. alot of women get abused from their loved ones. they're all over the newspapers. but you know what? you're now stronger. if you think about it, when he pleaded for you, you accepted his appology, which proves you have a heart far more special than anyone. and when you went to the police, you let him go, which proves that you've evolved. you're stronger now. i would imagine him feeling very small after what he did.
don't have any regrets. dont ever look back. its only a harsh way to bring back the tears. i can imagine you must have been very distressed, and probably still do...just keep in mind that all your friends and family are there to support you. don't worry about bruises either! they look cool! and besides, you can claim insurance for whoever installed those sound-proof doors your mates have that they didnt hear you! i hope you'll feel better soon.
