Why men ignore women that like them?

A myriad of reasons come to my mind.
A few being -
Self protection?
Non committal?
Untrusting?
Been hurt in the past?
Emotionally insecure?
Too busy to have someone in his life?

A relationship would interfere with personal goals ..,

Same reason some women ignore the men who like them in favor of the ones who don’t call and treat them like crap. It’s a people thing.

Because they aren’t particularly interested and like to play games

They don't like them back the same way

Well, one reason right off the top of my head

Perhaps they are wondering when the other shoe will fall...

They are not worth the time ...move on

I don't ignore them... they just don't like me...

Because it is a matter of push and pull.

No idea. It's never happened
