does that mean i'm not really cut out for this?
No, I'd say you're very
cut out for poly!
Why? Because poly isn't about just sex. It's about having, multiple meaningful relationships.
That is not to say that a poly person couldn't also have casual sex with people who are not committed partners, but that aspect would be considered "open" rather than polyamorous. Though your relationship with her started out as primarily sexual in its focus, obviously it evolved to include more heartfelt emotions. You cared for her and wanted her affection, and that was more important to you than the sex. That is definitely poly.
I think you should pat yourself on the back for not putting up with a situation that you knew would demoralize you and make you feel worse. Sure, you might miss her, but you stood up for yourself and that is always a good thing.
