you mostly have positives from him and efforts that he probably feels are not being acknowledged, let alone appreciated.
D1's pain is a drag. I have been there. These days h and d1 are in frequent contact and he takes her out to dinner or lunch, one on one, monthly. It was my suggestion and I have to admit that at times, I was a little jealous. But I really want their R to be as strong as possible for lots of reasons.
They can repair their r's. It won't make up for everything but I'm a veteran and we know many families with fathers who miss out on a lot yet stay close to their kids or reconnect when they return after long absences. It is not totally the same but there IS a rebuilding.
Give your h some credit, try not to doubt everything he does. In fact, I would suggest you applaud loudly for the 1% of positives he does...yes, I know it's hard.
But he does seem to be trying and you don't want him to wonder if he'll "ever be good enough" so why should he bother trying?
