Staying together for the sake of the kids is never the right choice. They see the relationship dynamic and become confused or upset or think that this is how a relationship should be.
This is not healthy for ANYone. He can threaten all he wants but in the end it is not him that decides custody - it is the judge and there is no reason you wouldn't or couldn't get at least 50% or better custody AND support from him (financial) for the children. If I were you, I would leave.
