Re: Husband texting female co-worker...
Have a friend leave 200 text a day on your phone and then leave it out for H to find, and see what your H feels about that.
Then call the friend and have him or her tell your H to quit texting so much.
I doubt that will happen, so tell H your having a affair and you want him to leave for the week end. He will jump at the chance so now your really screwed. maybe not, try it!
At any rate you marriages needs a tune up NOW, go to a hotel this weekend and have sex, treat him like a king.
That will give him something to text OW. maybe sneak in a pic of the both of you, on his phone and send it to OW.
Know I'm getting out of control here, good luck and trust me be "that women" your marriage depends on it. Just do it smart and quitly, then make your move when they least expect it, if you have to.
