Why did my ex move on so quickly?

Of the ones I was able to talk to about it all rationally later, some of them admitted they “used” a new “hook up” the same way some people use drugs, to dull the upset over our breakup; some said (perhaps as revenge) that I was easy to replace; some said they just got lucky. Most didn’t stay with the quick replacement, but a few even “panic married” the replacement, as part of being upset about the breakup.

Different tack: I don’t think you asked what you want to know, you asked what you’ve heard other people ask.

What I suspect you really want to know, is one or more specific questions.

If you were to bet, will Canada bend over to Trump's America demands or remain inflexible until the last day of his Presidency on January 20, 2029? Will America or Canada win this geopolitical arm-wrestling? I'm rooting for America.

Such as, if your ex moved on fast because they never actually loved you;

or if they moved on quickly because they were secretly starting up with their current person before you broke up;

and so on.

Why do most men who date ugly women brag like it's some big accomplishment, when any guy can pull an ugly woman?

or if they moved on fast because they can control their emotions like a simple light bulb;

I know from my own “misadventures” in love, that my ex’s were able to move on quickly because they were more attractive than I am, and far less shy, and sometimes because they were far less picky than I am.
