Just like many of you - I doubt if i will ever forget BD. I don't remember the exact date anymore, but it was in early May. Probably around the same time as you J if I remember correctly.
Came home from work, made dinner and we had a great evening. And then kids were put to bed and dishes done and exW sat me down at the dinner table and told me that she wanted a separation. It hit me like Whoaaaaa!! What a whirlwind of an evening, and the next weeks that followed. It all kinda became a blur. I do also remember the exact conversations I had with her about trying to make it work. The last one was in October 2017 - she had long moved out and I was just waiting for our house that we had purchased a year ago to be possessed by the new owners by the end of that month. I had gone over to her place and sat in her small backyard and had a glass of wine and poured my heart out and said I was willing to put in the work. Her exact words - this separation is permanent. I had been DBing by then and I told her straight up that I was taking her words exactly as she was saying them - no subtext, no reading between the lines. She said she was done - no second chance, no nothing.
I walked out of her place that day and didn't look back. I sometimes still wonder if I had done something differently, maybe we would've had a chance. But I know it's all futile thinking and the ball was in her court and she didn't blink.
I know that I did everything I could and so I have zero regrets. I have carried myself with dignity and self-respect.
