OK, so I am glad I added my small print 
Have to confess to NOT liking the Gets Angry Very Quickly bit. The throwing the phone thing too. Not Happy with that one bit.
How long have you known him in total?
I'd still - at this stage - say that you need to talk to him, you need to start out saying that you are not coming to argue, to tell him off, to fight or to blame. It's pointless.
What you are interested in, is making sure that it never, ever, EVER happens again, and also tell him that you need to make sure he knows how it has made you feel, how upset you are over it and that you need to talk about it with him.
I'd also re-state that you are speaking about his to ensure it never happens again, and that if he so much as raises an eyebrow in your direction, he will have to leave.
This conversation would deal with the bits you need to get off your chest, and do it in a non-confrontational way, but identity the consequences.
If you still can't shake the bad feelings, then perhaps call Women's Aid or go and see your Doctor and ask for a referral for counselling.
Again, I would only advocate this sticking with it if everything else is OK. If he is verbally or emotionally abusive, then GAME OVER, seriously.
How equal is your relationship?
