Parents don't always know that the relationship their AC is involved with is manipulative. The manipulation occurs over time.
You can start to see less of your AC and have less contact but not say anything because you don't want to be possessive of your AC. The annoyance you feel when on more than one occasion an arrangement to meet up is cancelled at the last minute, is kept to yourself.
You want your AC to be happy and don't want to be a source of discontent in their relationship. You want to get on with their partner, make them welcome and feel they are a part of the family.
It takes time before you, as a parent, other family member or friend can see what's going on and depending on the length of the relationship, the extent of commitment that's been made and the depth of feeling the 'victim' has for their abuser it can be too late.
It's no coincidence that a number of estrangements occur when the first child is born. When not just the relationship with the partner is significant but the desire and need to maintain the family unit for the sake of the child becomes paramount.
It was only with hindsight that we were able to see what had been going on for months. What began when she became pregnant and proceeded with alarming speed once our first GC was born. When he was just 8 months old, we were disposed of.
Not long into our estrangement, our ES told his brother that he'd told his wife he'd given everything up for her. There was then a point when he realised what he'd done, maybe he felt he was in too deep, that he might lose his child if he didn't go along with her demands.
I guess we'll never know but he was right, he did give up everything for her.
HolyHannah you've posted "Dismissing what I am telling you as personal fact/truth is disconcerting" perhaps you could remember that when you dismiss the "personal fact/truth" that EP's share on GN.
Terrible relationship with DIL - am I the problem?
