EC you are finally alive.. great to see the 2 x 4's have finally connected... It's been a long battle but I think you are finally there!
Have you shown MIL what your H has been saying about you behind your back? I am wondering what it would take to shock her into giving him the boot...
Don't take what he writes to OW too seriously.. he's lying to her too remember.. SHE is being manipulated as much as you...
Don't feel sorry for her, she's part of the lie as well.. Just showing you that these two are NOT on a solid footing and the affair won't last long term... No honour among thieves my dear.. there truly is no honour among thieves...
