DH had been more or less NC with his parents for 20 years. We did exchange Christmas and Birthday cards and they sent cash in DC's. All a bit of a nonsense really, but to begin with I fully expected it to blow over and then stopping seemed like it would be a big deal.
They always thought the "trouble" was down to me, but it really wasn't. In fact it was me who encouraged DH to keep in touch for years before the final straw, when probably I should have recognised DH would be happier without them. And he was. It was hard for me to see it because in my family, although we fall out, we make up and everything's OK again. Theirs was completely different with grudges held for years.
DH died. He was very ill for about 6 months and adamant he didn't want them to know. He left them a letter explaining that it was his decision, that I was to post after the funeral. He didn't want them to come and make a scene at the funeral like they did at our wedding I sent the letter as instructed, with a short covering note with dates. I have heard nothing at all since and they have stopped sending birthday cards to DC.
My Dad thinks I should try and become civil with them for the sake of DC's inheritance. I've no idea what there is, but they do own their home and have only one other GC. I think no one needs an inheritance that much and it would definitely come with strings attached, even if it happened.
I did feel bad for the fact that they hadn't been told, but the not even sending condolences or getting in touch to see how DC are and cutting them off, just proves DH was right to my mind.
Or am I letting DC down by not making more effort?
It's not that Dad is being grabby, he's genuinely concerned that DC are being deprived of something that should be theirs. FWIW DC will probably inherit well from my parents (although hopefully not for a very long time)
