<human>: Can you give me a shortened version of the text?

My girlfriend and I have been together for just over 4 years.  We share a home, 4 dogs, we laugh together, but deep down in the core of my being, there's this nagging voice telling me that she is just not the one for me.

This sucks.  This means I have no choice but to destroy the woman that I've built a life with for the past 4 years. Relationships are cruel when they don't work out. You're forced to crush someone you've spent your life protecting and lifting up.

Complicating the issue is the emotionally fragile nature of this particular lady. She has a history of eating disorder and a family history of mental illness, and has declared her dependency on me many, many, many times. She has flat out told me that she would die without me. No pressure.

I'm a people pleaser and would almost rather spend my life in an unfulfilling relationship than to deal with the fallout of going through the breakup.  I just can't fathom seeing her reaction. That pain in her face. It kills me to think about.

I think something that would help me prepare, and give me some perspective, is if you would share your worst breakup story.  Explain the fallout. Explain how awful it was. Or perhaps it wasn't as bad as you thought it would be. Etc.  Perhaps I will find strength in these stories.
<bot>: I'm trying to muster the strength to break up with my emotionally fragile girlfriend. I think hearing a story about your breakup might help.
