It is not a rigid way of thinking, it is dealing with a situation. My XH sees DC as and when he feels like it, sometimes going weeks between visits. I gave up Mothers Day with her this year as he asked to see her as it was right after her birthday and he hadn't seen her for 8 weeks at that point. I don't need a special day, I have her 99% of the time thanks to his lack of contact.
So no, I am not in a rigid way of thinking. it is simply not my job to think, oh its Fathers Day this weekend, he hasn't asked to see her, what if he wants to, what should I do etc etc.
I spent years thinking he might want to do this, or might want to do that. i gave up when he went abroad the week she started school, when he didn't want her on Fathers Day, when he doesn't send her a birthday card, when he can't even be bothered to text her once a week.
But of course I should forget all of that in case he wants to see her on Fathers Day when he can often go weeks or months between visits......
It's not about point scoring, it's about a grown man being responsible for his own actions in life.
