Not judging BF just my opinion. Full detachment and forgiveness is hard. I don’t push it on myself. If it comes it comes if it doesn’t that’s ok too. The most precious thing for my kids and I is time spent together. This was taken from us with zero say in the matter. It’s something we can never get back. Was part of it my fault? Absolutely. But I was willing to do anything to fix it. For me it’s hard to forgive but I imagine I’ll get there some day. I just won’t force it.
