Things are unlikely to get better. Because abusive partners rarely accept responsibility for their behaviour. And nothing you can do will make any difference at all.
Frankly, you are only one step away from tragedy. So make plans to be able to leave the house with your children at the slightest sign of trouble. Because the situation may quickly get out of control.
Later, make sure your husband understands that you won't tolerate his behaviour. Say what you will do if you feel threatened in future, and do it. Such as spending the night with relatives.
Do not cover things up. Talk to a counsellor and try to get your husband to also see a counsellor because that is the one thing that might help. And start planning to end the relationship. For your safety and your children's.
All the best,
Chris
