By hooked up-I presume you mean you slept with him.
I'm sorry but I don't think he is the one for you otherwise wild horses would not have dragged you into that situation -either that or you are very immature.
Don't be at all surprised if he can not forgive you. You've broken this trust by doing the unforgiveable-if you can make a go of it -then you have been very lucky.
If not and your relationship fails-next time you meet 'the one' you will take great pains to nurture it-so that sort of behaviour does not happen again.
Mature people who get mad with the people they love-do not use such destructive behaviour to get their message across
