BL for me it was i would look back at specific snapshots of our life. Taking the kids to the beach, going to see our favorite band, sexy Saturdays. All minor parts of our life. Forgetting that basically every day she was biotching, yelling about something.
Those are all faded memories now. There is absolutely zero conflict in my life right now. I have raised my voice to the kids less then a handful of times in over three years. No lie.
The funny thing is my son called me to come over a few Sundays back and I could hear biotching about a phone charger in the background and I had PTSD about it. Seriously it was strong.
I still think my marriage was fixable if she put in the effort but as Steve says the number one thing you learn is you can only control you.
