My WW told me similar things one time. That she was done running around and was going to move back home, but she needed one more weekend out to "get it out of her system". This was after I told her I knew about OM and didn't want her hanging around him anymore. At the time, my mind thought this was acceptable. I believed all the BS and thought when Sunday night came, she would be back home and willing to work on the R. She did stay at home Sunday night, but ended up having to "work late" every night after that. It's not that she wanted to come home (she sounded VERY sincere), but it's that she wanted me to shut the f up and stay out of her fantasy. The only way to sell it was to be sincere. So off she went shopping for plan A, while I was sitting at home being plan B worrying about what to do next so I didn't screw anything up when I was already screwed from the get go...
Believe nothing she says and half of what she does. Any WW that truly wants to save the M would be there in a heartbeat and bend over backwards to make things right. Not going out with her friends for the weekend. Have no expectations and be prepared...
