She just got to enjoy it a hell of a lot more than I did. Some days, life truly can be a bitch!
"Affair " sounds lovely like something people do after brunch
Indidfety, betrayal, adultery
Is when your partner shares their gentailia with someone else unbeknownst to you while they are still sharing their genttalia with you
In today's world that means putting you at risk for stds
It is admirable that you want her to be happy
It also sounds like you may be swallowing her blame shifting...
Don't
I have gotten back into physical activities like working out and riding my bicycle which I haven't done for several years now. However, there is a hidden agenda behind that. She at the time of the affair was 47 and he was 29. Extremely physically fit.... need I really say more?
