Hi T. Well, so sorry to hear that things took a dive again. Unfortunately, this seems to be the pattern for your W. I don't know how much is lack of maturity, selfishness, contriving, or mental illness. I use none of those words to be snide. If she is playing you, it is wrong. Period.....done. If she is simply so immature that she lives in the moment for whatever good feeling she gets from it, that's unhealthy to a R and calls for serious therapy. After all, you can just blame so much on immaturity! She's raising your sons, and you hope she would have a better sense of right & wrong. However, her scale is obviously not the same as your scale of what's right/wrong between people who say they will work on the R. (Did she ever say she would, or was it still just one toe in?)
Last, there is that chance she's bi-polar. We certainly can't determine if she is or not, but if she is...then any efforts improving the MR for her would probably not stick until she was on regular medication. I'm not saying it would fix everything, b/c it still takes the hard work.
I'm not telling you anything new here, T. I don't blame you for being angry. She has put you through the wringer. I'm not even suggesting what to do right now, other than take several days of no more contact. Cool down. Don't call about future events coming up, b/c you are too upset and it will lead to more fights.
I have to leave for a few minutes, but I will back to discuss a couple of things that kind of jumped out at me.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
