Since exit is not a choice you choose to make right now, consider these options to get the husband to soften his stance:
1 – make a note of the way / words used that are abusive or non-supportive
2 – if its a real tirade of verbal abuse, consider making a recording, and then in a quiet moment, play it back for him so he hears what he sounds like
3 – impress upon him how bad an example or how much it undermines you as a mother for the kids to see you treated without respect
This is if the abuse is verbal. If C”V the abuse is physical, there is almost no chance of him getting better. Leave while you still can. Nothing should take presidence over your safety (and that of your children, who are possibly also at risk)
