He scares you! And of course he promise you do not hit you. All the people that hit their partner also promise to never do it again and still... In their rage they can't control themself! It will get worse with time. And that he doesn't want to seek help... even though he knows he has a problem and it scares you.

Do you want to live in fear, waiting till he finally hit you? And what about your future, do you want children? With this man?

Run now while you still can and are unharmed.
