My fiance, whom I had been with for close to eight years, left me out of the blue. No warning, no discussion, nothing...

Thanks, used to daily. Don't think I will be for a while.

notI've been in a few break ups, nether been in a relation for 8 years but got close to it one time.
Time will ease your pain, try to find something you like to do. And if you find nothing try to be with people you like. And if there is no one, try again tomorrow. You'll get over it eventually, not knowing when.

You're the problem then if she hasn't been happy in years dude. Cut her off, and chill out for a while. Then look for love again

In my experience, solitude makes the suffering worse.
When we're alone, we reflect, and then overthink.

Seek company, anything is better than being alone.

Stay strong OP. Last night I had an argument with my fiancee and she wants to 'think' about us for a few days and won't deny nor confirm her feelings or thoughts. To be honest, it's pretty clear she has her mind made up. She's at work right now and I'm just sitting at home losing my shit. I know her two days to think or whatever is merely delaying the inevitable, or at best mind games but she's not like that. All these questions you're asking yourself are eating me alive right now. I've gone through breakups before, but never after dating for this long, living with someone for so long and being engaged. Maybe I'm wrong. But her vagueness and attitude says it all. Totally out of character.

Also, general breakup wisdom:
Women and monkeys, never let a branch go before they have a hold of a new one.
