"what a shame your daughter chose not to see her dad based on his relationship choice. It’s a form of emotional blackmail to say I won’t have a relationship with you if you’re with XYZ, and is unacceptable from parents to children but also the other way around, no one has the right to dictate who other people are in relationships with. she should have been encouraged to see him separately, no need for her to associate with OW."
Wow @Gensola, you jumped to a lot of conclusions with that!
9 times out of 10, it's the father with the new, younger woman (& often subsequent new baby) that reduces contact/time with their DC.
If the children already have a strong relationship with their father and he continues to prioritise them, even after splitting up the family home, then usually those strong relationships continue.
DCs who "lose" a parent to an affair, rarely do so willingly; most often they parent-please to the Nth degree to get the absent parent to stay in their life.
But having sex with a 17yr younger woman is often seen as preferable to the exH than taking his kids to the park/helping them with their homework/doing the school run/washing and cooking for the DC - you know, all those parental tasks that the resident parent has to do.
It's the daily small bits of parenting care that create the foundations of the parent-child relationship and when those foundations are destroyed (by cheating, lying and subsequent moving away) the absent parent not doing those day-to-day tasks should work really hard to give their DC new stability.
The onus for that should always be on the adult that broke the foundations in the first place, not the child. The child isn't "emotionally blackmailing" their absent parent by asking for one-on-one time; they're asking for proof and reassurance that they haven't been replaced by Dad's new and shiny OW.
