So - did you break up with him before, or was he just not calling?

I ask because I can see a pattern in my younger days. I’d start dating a guy, be interested and hoping it would turn into a relationship. The guy would appear not that interested - either making dates infrequently, or not in advance. I would decide he wasn’t that interested in me, and give up, moving on. At times that was certainly the right interpretation, but in retrospect, many of those guys just needed more time - I’ve been surprised to find out later that to some of them, I was the “one that got away”.
