DH went NC about 10 years ago after years of unpleasantness and me keep smoothing things over. In hindsight I should have left well alone and it would have happened sooner.
However, I was coming from the same place as my Dad is now where family is something to be cherished and where even though you disagree and fall out on occasion it's impossible to imagine that life could be better without your family.
There have been a few bereavements in our family recently which I suppose focuses the mind and my Dad has started "talking" to DH about it all again (he did it a lot when they first went NC) Dad really thinks it's an awful thing that has happened and that despite everything "she's his mum" and DH should make things better. He means well and I fully understand where he is coming from (having been there) but I don't know how to make him leave DH alone.
