After my husband came home from drinking, I casually told him about his child (usually it's not called a thing at all), and as a result, he lost his temper, and then we quarreled.

For the first time, you should give him a chance to understand, which will better show off your kindness. You live with him, not your mother-in-law. Mother-in-law said that when her husband didn't drink, she half-jokingly and half-threatened that abuse was illegal, and he would go to jail if you reported it. Take care of yourself. Besides, you still have children. Divorced children must have a shadow. That's also your responsibility. If he commits another crime, it's another matter. At that time, the court will support you even more when you are divorced. So let him live now. In order to set off your beauty, take a step back. Maybe he has already regretted it, but he is just not good at expressing it. If you really leave, you will meet someone good, so giving him a chance is the best policy.
