Welcome, fastjon! Where are you in the divorce process? When you have a moment, feel free to tell us a little of your backstory.
Thats one of the hardest parts man. Going from feeling special to feeling the exact opposite. Just remember it's not you, even if you have some bad qualities, no rational person jumps from such extremes.
I am right there with you, I just got left 2 months ago but for another "man" and it will be a divorce too once the timeframes are complete.
Just remember, it seems they can never be reasoned with, the truth to them is what they see, reflecting and recognizing their part is never an option.
