Very sorry to hear things are getting worse. Perhaps your return was construe as something it was not. You don't have to settle...you shouldn't settle. Trust me lives too short to live (?)amount of the time in pain and anxiety. You know what feels good, or right ...and you know what feels bad and wrong. Go find the good and right fitting. This might never really work for you no matter how much time, therapy, behavior modification techniques are used.
Trust your gut on this...
The numbers actually work in your favor.....millions and millions of women want to be the sole focus of their husband/partners romantic interest ...go find one of them.
