Another big thumbs up for Smileless and a huge thank you for all of the time, patience and kindness which she finds for us all.
muffin, my heart goes out to you. Your situation sounds very similar to mine. We were a close, loving family until DD1 met her now DH, from whom we gradually became estranged. We have seen her once in the last three years. She ghosted us for 6 months, moved without giving us her address, got married without telling us, and gave birth to our first DGD, but did not tell us until DGD was 14 months old (and only after we had agreed to give them a loan to buy a second property to let out).
DGD2 was born on Christmas Eve, whom we also haven't met yet. We are due to visit in March, but my DH has just been diagnosed with an aggressive form of cancer, so I suspect and hope that he will be having his treatment then, so we will not go. I seriously wonder if he will ever meet his DGDs and it is hard not to feel bitter, although I am not generally a bitter person.
I suppose it's a positive, but DD1 has been in virtually daily contact since last summer, sent lots of photos and videos of the DGDs, is clearly devastated by the news about DH. And I know that I need to move forward, for DH's sake - who is much more forgiving than I am - as well as my own, I just don't have the headspace for negative feelings.
I totally agree that it is about 'power' and the reason I don't like SIL and fell out with him is that he is controlling. DD1 didn't just estrange her family, but all of her friends as well. Neither she nor SIL are working at present, so they are together 24/7 and they don't see anyone else other than his parents. They think that they are doing us a huge favour to have any access to 'their' family.
Sorry to be negative - if DH can recover and we have even a few more years together, I almost don't care. My perspective has altered. DD1 has her own life to live, with all its ups and downs, and I wish her well. I still love her but I have been hurt too much and, like Smileless, I think it might be better not to meet the DGDs, as then there is a vulnerability. Now I just see pictures of sweet children but, frankly, they could be anybody's. I have no connection to them.
