What makes some men consider certain women gf material vs wife material?

Anonymous
In my area and other places, I still see plenty of men getting married with ages ranging from 22-30. My male cousin was the youngest to get married to his HS sweetheart and he's only 19, which in my opinion is too young but ok if he's happy fine.

So basically all this feminism and fear excuses goes out the window. I thought men were scared. It doesn't sound like marriages are going to disappear.

This has me wondering: I already know how men can distinguish a girl they just want to have fun with (usually girls that are into sex early and also want to have fun) but no strings attached vs the ones they want a serious relationship and more than just sex.

But what makes a man actually want to be engaged to a certain woman vs keeping others as just a gf (even though she never slept around and has good qualities) and not ever wanting an engagement even if more years were to passed?

It seems like deep inside, they do want to form a family but will only consider certain specific women for it. But if both women have great qualities, they are some proposed to and other can be staying at ''forever gf'' status

even if the man actually wanted marriage in the future but just not to her.
