djhartm, thank you for joining in, and you make some valid points. The problem is I don't have a choice having her around my family. The sons are adults, so it is now their choice.
Anotherstander, I agree, I am going to the party for my son and his fiance (her 21st party), not for any reason to do with the W. Yes I think it will be mighty uncomfortable for the W. Even the future DIL parents would be going what the .....? Unless W and OW decide to a. leave early or b. sleep in separate tents. Again who really cares what they do. They can spend all the time in the world pretending to everyone.
ME:51 W:46 M:25 S:22, S:20 Divorced 16/9/15 BD 10/12 W left 12/12 with OW, affair confirmed Nov/12. Dark since 6/13 I"m in a new relationship since Feb 14.
