It is all her concern for herself. Every bit of it is about her!
Ok. I need to do what works, but what do I do or say about these things she is saying?
Get disgusted and STFU.
Validate feelings,
stop validating behaviour and feelings on the A and the consequences of it. Hold her feet to the fire.
I think some work on validation and what it is may be in order. Validate things that are of real concern, such as her car broke down- That's rough WW, I am sure WW you can sort it as you are resourceful. She broke her toe "ouch WW that must really hurt"
But "my A is going too well" that you do not validate.
stand ground on affair being solely her choice and wrong?
You are really asking this? Is her A really your fault? Did you cause her knickers to fall off for a dingbat scumbag to deposit his comings and goings?
Do you not think her A is wrong? Are you OK with her A?
