Oh man, I'm so sorry. Just remember these WAS's have a way of rewriting history. IT's part of the journey. The I've been unhappy for years and years bit. My H started with being unhappy for 6 months, then over time it went all the way back to 2 1/2 years ago. It kept changing. And all the while like you, I have cards, letters, memories of great times,.........but all of that got erased in his head.
Try as hard as it is, to not let this heated argument overtake the whole journey. You both were heated ,it's easy to say things you don't mean, and even easier for them right now when history is so muddled up in their heads.
You have got to try SO SO SO hard right now to GAL like crazy. You've got to leave the "crazy" behind for a moment and focus on getting yourself in a stronger place for you and your kids. Seriously.......... take the focus off of him and your relationship right now. Focus on doing things that bring you joy and peace. Surround yourself with those positive people in your life, and ONLY communicate right now about the kids/ schedules, just the basics. It WILL be noticed!
