Regrets and realizations

You ever meet someone that seemed mostly perfect. But, in the long run didn’t get that “feeling” so you broke it off with them. Only to realize months down the road you were completely wrong. No one you meet matches them. And it was you that was the problem? I broke it off with this women 6 months ago. She was upset, but moved on like a normal human. I was ready to keep dating…to find my “person” only to now realize she was it. I don’t know if she’s dating? But I do see she’s an active on social media, and meet up groups. I keep hearing these songs that remind me of her. I want to reach out but not sure how. I’m still not even sure how I feel. But, I do know want some more time with her. Door was left open when I broke it off. But we’ve been no contact mostly since.
