Cheating

I have cheated on me boyfriend about 3 times and he only knows about one. When I told him we was in the middle of making love. He kept pressuring me to tell him and confess, so I did and he took it bad kept crying and was trying to kill himself. We working it out now but he think I cheated on him more than once, which he is right but I can't take seeing him hurt again like before so I didn't tell him about the other two guys.
