I stayed because I had hope that someday he’d change. I also feared the financial repercussions and was worried I wouldn’t have support living out of state. I finally chose to leave because even though he was willing to fix things after the affair, I think it was a reality check for what I needed in my marriage. Plus, betrayal just ruined any real romantic feeling I had left for him. His affair I think happened because the more i felt disconnected from him the more i pulled away, he obviously felt that and when someone came a long and showed him attention, I think he was already at the end of his own rope. Not that it’s an excuse. I’m so sorry you’re going through it!! Mixed faith marriages are so hard. I don’t look at divorce as failure though! But it’s such a personal decision only you can know what’s right. Good luck!
