Why some guys get scared or just run away when a girl likes them?

Because it´s a new situation for them and they don´t know what to do. For guys it´s a rare thing if a girl is openly showing interest in them. For a guy that´s rare and so they might be shocked and overwhelmed.
The girl that likes me right now, doesn't want to date me because
1. She's "too busy"
2. She's been hurt too much
Yet, she still claims to like me, after all the time weve known each other (10 years)
They're not used to it/insecure/uninterested.
Or maybe just doing it because of a dare/brocode? I don't know, you're under 18 - kids will sometimes do weird shit for no reason.
Guess what it’s not only guys lol.
Fear of being vulnerable I guess

The same reason some girls do; immaturity and an inability to handle emotions.
Guys who do that aren't ready for relationships and dating, and they are very insecure.
Because girls have cooties
Have no idea how to deal with the attention

Girls are scary sometimes.
because they don't feel the same
LOL. Get a journal.
Immature, just don't know how to respond
Too shy, low self esteem
They do?
