I’m so happy for you! And it is wonderful that you get along with the in-law family! I’ve always gotten along with that side of the family(s), it makes life so much better.
My oldest son is divorced but I still get along fine with ex DIL and her family. When I go to visit I stay with her and kids as my son has roommates and no room for me, and he’s fine with that. But I pray that NEVER happens with your son’s marriage.
It’s great you get along with them so well! I think it would be the same for us, but as you said I pray it never happens. My biggest worry is that they won’t be able to have kids as she is vaxxed (but not boosted) and she has had issues surrounding her period since. They want kids so bad, and we have put it all in Gods hands
