Your story is similar to mine also and your d day is concurrent to when my WH's A was going on. I didn't find out until 3 months later and the signs were there for me too, but I was too dumb and trusting to see it.
I go back and forth between this total rage and just thinking that the OW is sooooo irrelevant that it doesn't matter.
I made my WH quit the job. But the slutty tramp is still there. Whenever I am forced to be around her I feel like I am about to have a panic attack. I wish that I had pushed her getting fired at the time but I was so beat down and insecure after finding out that I felt like I was frozen in my tracks.
It infuriates me to see her laughing and joking with people at work. No the bitch does NOT deserve to be happy and have friends and I resent the people who even talk to her.
But you know what I didn't do anything wrong and have no reason to hang my head.
After some time, IC and the fact that my WH through her under the bus like the piece of garbage that she is, I have found a way to deal with it at work. I fuck with her and make snide remakes every chance I get, only things that she would pick up on and nothing illegal or unprofessional really. One thing that really gets 'em is to talk about your MARRIAGE and your HUSBAND and what FUN PLANS you have this weekend and HOW LONG we been together. Kinda burns them I think to see that spreading your legs didn't get you anywhere except a reputation of being a whore.
Fuck the bitch, don't do anything crazy. The rage is gonna be there for awhile but why mess up your good Karma by doing something bad. Her own Karma is gonna bite her in the ass someday...in a big way. I just hope I'm there to see it!
