Why do men who rejected you always come back?

I’ve had ex boyfriends and ex crushes make a reappearance into my life, when one minute they were acting like they hated me, the next, years later, they’re trying to impress me. To the point where I have to actively avoid them on dating apps. Or avoid using some of them altogether.

It seems like they were embarrassed or insulted by the thought of my having been interested in them years ago. Note, I am pretty but fat (because of my medication causing weight gain); and I was fatter and less pretty then and more of a try hard.

Have these men matured and have I improved, or are they all just realising that I was the best they could do? (I know at least one ex boyfriend and one ex friends with benefits were just desperate).

I have no intention of chasing these men. I just am curious as to why this almost always happens.

I’m not always prettier when they try to come back, but I usually am and more confident.
