I know - believe me I know. I have been trying to GAL, stay busy, PMA all of that jazz but in my heart of hearts I keep thinking "How could this have happened".
I don't have any answers. Love is a losing game as Amy Winehouse famously sang about.
Maybe after the passage of time we will have a better perspective.
Love yourself, you are worth it and you are more than Your relationship with your husband. You are YOU, perfect in every way. Keep repeating that every day!!
