My husband has 3 kids who are all adults and we have a teenager together. The Ex took them to live in the US right before we got married 16 years ago. Visits have been years apart, contact is rare and sporadic ( the oldest SK now has 2 boys 3 and 6) the middle SK came back home to the UK 6 years ago and we set up her own flat, got her a job and she's now in a relationship and about to give birth to her first child. This brought us so much joy as we can now be active grandparents without the distance being a barrier.... The Ex has come over to help with the baby ( not arrived yet) but the 2 SK and the grandkids have all come over and staying with the expectant mother and her partner. I don't think this is an ideal situation but that's how selfish they all are... we are anticipating some contact with them during their 3 week stay over here but each visit causes me anxiety and friction between me and my husband. Any suggestion on how to deal with this?
