I know I can change, but at the rate things occur for me, it won't be easy and this turn of events definitely doesn't make it any easier.

I mean, how are you supposed to react if someone just dumps you in that exact manner? In that context would you not feel you at least deserve to know why and how you messed up so badly that they felt you didn't even deserve that much? I don't understand why I'm seen as such a bad guy here when I literally haven't done anything but be understanding of her needs and wishes, save for this scenario where I do feel entitled to knowing what I could have done better or why I was so terrible of a human being that it ended this way.

She wasn't my sole source of happiness. As I stated before I'm completely satisfied with every other aspect of my life and having a partner is what makes my life complete. I have absolutely no complaints about my life and no issues being happy without a partner. Calling me delusional doesn't really help anything. I feel you're severely misjudging me under little context because I've stated multiple times how I've even gone out of my way to not be needy, clingy, or exhausting one bit.

I have no problem being self sufficient, I don't know where you're getting the impression that I depend so much on a partner that they would feel exhausted and pressured. How are my expectations unfair if I don't have any? The only expectation I've had so far is an explanation for why she felt this way.
