Think about it from their point of view.

Say you were being hounded by fat girls morning noon and night, most of whom being idiots. You'd get defensive before you were even adult. My ex even had a stalker. That's what it's like being a girl, a lot of people who you are not interested are staring at you and harassing you all the time.

Just accept it and let it go. If someone likes you you'll get their number. Focus on what you can control, which is: you.
