Sorry if I'm bringing everyone down, just feel like I got hit with a baseball bat right now.
Believe it and forgive yourself. Dig real deep and do the exact opposite of what got you here, that is Where you failed in your half of the marriage. She has the same obligation, but you can't control/fix/manipulate/or convince her. So guess what? You can mope around and be sad all you want, but as soon as you forgive yourself and DO THE WORK FOR YOU you're your own worst enemy.
If it makes you feel better, you are not bringing me down. In fact me posting to you reminds me of where I was at one point, and I know you can get to a better place too.
Look at yourself in the mirror and say "I owe it to myself and my part of this marriage breakdown to be the BEST me possible." And Moose I can't emphasize this enough, you do this for YOU, NOT to get her to notice.
