I think I need to buy a big STOP sign and paste it in front of my desk. To stop myself thinking about OW all the time.
I used to need to STOP myself too and must admit mow a year later after the BOMB.. I am in a much better place just this past month... .....but I honestly believe that we hold onto the OW BS longer than they do.... as my H was depressed when he broke it off or when he told me they had a fight like if I was his Roomate and not his wife of ten years I almost passed out!!!
I also a few times would confront him @ OW,, when I needed boundaries .. and to keep my sanity. Try to stay calm and try not to think of her....
I know, I know easier said than done.... ....it took my H @3 months I would say to fully get her out. Contact stopped but he kept "reminders". PLus she is my SIL best friend so I still have to hear @ her! GUILT plays a big part in this too... he would say he didnt give a SH*T but then save pics she sent to him? Hang in there hopefully you did not backslide too much and maybe you just needed to clear the air? Hang in there you can do this just know it sometimes feels like it at a snails pace. God bless..
