I think you have to take what sandi said with a grain of salt. We don't know all about you sitch. So be careful about the advice you get here. I think you are doing the right things maybe just too available to her. Don't answer every text and try to make it so you don't see her as much and when you do make it short and be the one to leave first. detach..detach detach..remember you kids are young and won't be forever make the most of the time with them..make them your focus not her....My W told me all the same things and i reacted just as you have...I thought it was hormones etc...I just wanted the problem to go away and then wham we are in the same boat. be strong my friend....
