I had the A! So if I did why couldn't my W? Paranoia set in, I began questioning my W for no reason if she was having an A and questioned her about all of her male collegues (mental abuse)...I was haunted by the fear that my W would have an A because I opened up Pandora's box.
I've been trying to get my H to feel this. I'm not sure he had a PA or not and I never will be because of all the lies. But what I have wanted from him is to be sure he understood.
Now in regards to your sitch, I can say that just because you did DOESN'T mean she will. The paranoia will feed off of itself, first you think she will have one because you did, then it will be because you said she might, then it will be because you questioned her. You can drive yourself crazy and her. I never thought about it, and I honestly have kept myself so far from that possibility just because I know the damage done. So maybe, just maybe your wife won't do a tit for tat.
Try not to read into anything. Deal in facts as much as possible
