Dh's son passed away in his 20s 4 years ago. We've kept in touch with his widow as we, and the rest of the family, were all very close. She doesn't have any family in the UK and would come to visit for Christmas and summer holidays even though she lives quite far away.
We are still close and she's asked to visit again and stay, but to bring her new boyfriend. We are delighted that she's met someone nice and we like him and have met him a couple of times for dinner when visiting the city where she lives now.
It feels comfortable and nice to see her, and she's a link to DH's son, but this will be a new dynamic. Any thoughts?
