Well, there are many choices.
First, your hu*****and can give up the custody of these two children to their biological mother.
If their mother doesn't want them, and your hu*****and and you don't care about what happened to them, you can give them up for adoption.
If your hu*****and and/or you are still care about them, then stop *****ing and try to find a way to gain their respect.
By the way, it is hard to believe that "兩個小孩用辱罵、破壞衣物各種手段欺辱我,導致我流產。", unless they physically abused you.
