The reason I say women is because I'm a man dating women, don't nitpick.

If any woman you're trying to date isn't as enthusiastic about dating you, as you are her, she's very likely not to be actually interested and is keeping you in reserve, in case she runs out of men giving her attention. Or possibly if she doesn't find a partner she actually wanted.

You're always gonna be the second choice. Or third, or forth.

Dating a person that you're compatible with (what I assume you're searching for if you're looking for a relationship) should be your ideal. And simping after a girl just because you like her, doesn't mean it'll work out between you two. Even if it does. How do you feel that she had the need to keep you waiting, and potentially even go out with other men to make sure she's not missing out by picking you?

If you don't click right off the bat, it isn't worth your while.
