Do you actually understand the word integrity? I ask because you have used it twice, once about yourself and once in relation to what a mother should do for her children.
integrity [ɪnˈtɛgrɪtɪ]
n
- adherence to moral principles; honesty
- the quality of being unimpaired; soundness
- unity; wholeness
[from Latin integritās; see integer]

It is impossible for you to say how you would react to any other children your partner may have with a new partner. You might like to think you would act in a certain way, but I suspect that when you have been cheated upon and left to bring up your child alone, you might think differently. Equally, your DD might also believe, as your partners DDs appear to, that any new children are in effect, having their childhood, having the relationship with their father that they feel is their right. It doesn't matter whether that is reasonable or not. They are entitled to think it. As someone whose father left my mother and therefore us, for another woman and their new baby, let me tell you it bloody well hurts! Even now. 40 years later it still hurts. Don't you dare imply these women and their family are being unreasonable or unfair to you. They did not ask you to shag their father whilst he was still married to their mother. They dd=id not ask you to encourage him to leave them with an alcoholic mother whilst he pursued his happiness with you. And whether you like it or not, your DD is a constant reminder to them that their dad preferred to conceive another child with another woman than to be a father to them.
You clearly do not understand the meaning of the word integrity, because if you did, you would not have the gall to use it to describe yourself!
