The Kids are with Me or You - but not Her!
It's normal, it's real, and it's understandable ... so what's the answer? We all think it - and most of us say it when we share children with an Ex who has a new partner. The phrase 'the kids are with me or you - but not her' is equally valid when read "but not him" in place of her however 'her' just seems to be more common so for simplicity sake, I'll write with framing our stepmothers but this certainly does not exclude stepfathers.
