Thanks TTD180. Yes I accept the W is having an affair, the family also accept it. I now know the sons also know this.
The W is still in a fog where she believes simply stating "we are friends" is an acceptable reply to all people concerned.
I got to speak to the SIL and ex best friend last night. I learnt a lot of what is happening, how I am coming across (especially to my sons) and what changed everyone's views back in June/July last year. I will write that up another day.
For now though, I will wait for a few replies and then ponder my best action with regards to the party.
