Ok SG...what did we JUST talk about regarding the stalking?!?! Even when you find something out it usually is not what it seems AND you could never confess to seeing (or hearing) something or it will take you farther away from your goal. Now I am done with the hand slapping...
Your W just said those things out of anger. She was angry that you were spying and that you confronted her right then about it. I will say "good call" on the turning the scenario around! My H gets all serious and jealous if I mention dating or anything and (I know this is childish and I have stopped but...)I do it just so he knows what I am feeling when I get to thinking there may be an OW.
Now, oh king of backsliding, next time you feel the urge to spy... go to the movies, go to a batting cage, crank some tunes in your car (that is NOT parked in front of your apt.) and sing along while taking a spin (that is NOT on the streets around your apt.).
