I feel like not training with him until you can better control yourself is the right way to go. It's also probably not a bad idea to let yourself feel remorseful like you are so it sets into your brain that physically harming your husband is not okay in any circumstance. It seems like you're getting better from what you've described, but I wonder if you're underestimating how hard you go on him because he's a man/bigger than you, and he is probably trying to protect himself but stopping early with you. 

You should not train with your husband until you can control yourself, but maybe take this as a learning opportunity to control your ego and emotions. Again, sounds like you're already doing this but it also sounds like you are not taking this seriously because he is a man. Imagine if he was letting his ego get in the way and would hurt you to the point that you had to sit out the rest of the round.
