If I were you, and you truly love him, I would forgive him. He seems like he really regrets.
I would tell him that he has really hurt you, and that this is something he cannot do. I would tell him that this has broken your heart and a lot of your trust to him, trust he has to rebuild if he wants this relationship.
Then I would, if I were you, and truly loved him, give him a new chance. Take him back. Mistakes happen, and yes, I know from experience, mistakes like this hurt a lot.
But if he truly regrets, and truly loves you, and you truly love him, I reckon it's worth giving it another shot.
You can also tell him that you need time. If he can't accept that, dump him.
It will probably take some time before you feel the same trust to him as you used to, but in my opinion, if both people love each other and work for the relationship, it can handle mistakes, and it's worth working on.
