Yeah, that’s not applicable to all men.
I’ve wondered the same of some women

some are some aren't

Who the hell understands them?

Not true. Yet I was never the one breaking up.

Men learn to hide their emotions at a very early age. If they don't, their schoolmates will crucify them. The third ex, for example, NEVER revealed his hurt when I left him the first time, and when I left him the SECOND time the only emotion he allowed himself was intense anger.

We are practical.

Breakup happened... Move on. Why cry about it. If it was meant to be something solid, we'd simply try to sort it out. But mostly it's not because women aren't logical... They run on emotions.

The hardest thing a man can do after a breakup is pretending that it doesn't bother him.

Men are just better at hiding emotions.

The stoic thing is strong with many men, but often it is a mask they wear.

It's usually the other way around, women move on then come back 6 months later to check if they can still manipulate you after they done getting their cheeks clapped by the other guy.

Idk the guy, however men just learn it's best not to express your feelings in public. The guy is probably suffering a lot but decided to not show to the world
