Well i would say SHE"S A WHORE and her kids are fucked. Someday she will be a guest on Jerry Springer.
My parents divorced when i was 7 father remarried, mother never did. I am the only kid and dad never had any others because he had me. Step mom knew that going into the marriage, and nothing ever changed that.
I never had kids in my first marriage because i knew we wouldn't last. I had 2 kids in my second marriage, and that's all i want so i am happily fixed. Kids should never be used to try to draw people together, or in cases push people apart. If i ever get divorced i will happily tell the next person i have no need for any more kids, so if that's what she wants move on. But then again i would never get remarried...no reason to.
