Alright I called and left him a message saying something to the effect of . .

I don't care if you turn your back on me . . BUT don't you dare burn these little girls for HER. Don't you dare hurt your children. They deserve better than that from you . . . maybe I don't but THEY do. I told you you don't even have to see me . . I'll arrange for someone to interact with you if you would like . . . don't turn your back on your kids Kevin.

I don't care if it was wrong . . I had to tell him how I felt about what he is doing to them.
I almost hope it does push him farther away.
