Why do men only befriend you if they think they can form a romantic relationship with you?

Um, isn't that how it works? Especially if they started being your friend 2 years ago, just to get your love. I would date him if he has that patience. This lets you know that he's really serious about it.
The thing that'll tick me off is how they'll ghost you because they couldn't get you. Wouldn't mind staying as friends.
