I am 100% with you. Recently I've been making small steps towards reconciliation. It's important to take it slow and allow enough time for a sufficient break - meaning a couple months.
And keep in mind that you should live with intent, don't base your actions off of fear. Like don't text her out of panic that she will forget about you if you don't.

I had my first serious relationship from 19 to 21.
I had my second serious relationship from 24-26.
The girls I feel the way you mention, I had at least some sort of relationship with at ages 15 and 28. But we never dated, or slept in the same bed every night, or had to share meals together many times a week. So who knows how I would feel if I had, I don't feel that way about the long term girlfriends.
Maybe they were different, like I think, but maybe it never would have worked out with them either.
No sense in lingering, do something about it or move on.
