I would add, that I wrote my XH a lovely letter after he walked out, as I honestly thought that he was having some sort of breakdown after walking out with no warning.
The letter said how much I loved him, told him he was a great husband, father, reminded him of family times, etc.
He wrote back a letter that ended any chances of reconciliation, told me what a horrible person I was, how he had been unhappy for years, how I never appreciated him, how I had hurt him many times over the years.....
It is like he was in a different marriage to me, because he always seemed happy enough most of the time...... after ten years together, the only nice thing he could say was that I was a good mother.....
Anyway, his letter broke my heart and I ended up needing counselling to get myself to see that I wasnt that person that he had labelled so cruelly.
So don't do it to yourself, there is no point and it will only lead to more heartbreak for you.
