If you are an extrovert and you have an introvert gf/bf I have the best advice for your life .
If you started to have feelings for an introvert , that's not your fault that's mere greatness of introvert cuz they are such beautiful persons at heart .
Don't fall for them which you can't resist anyway , as an extrovert you crave to express your feelings but you don't hear any of them back . It's not introverts fault either they are just wired that way .

Better to save your heart from inevitable heartbreak that is waiting for you if you haven't committed yourself .
Last piece : Either you don't love them at all or you understand them so deep that you don't have to go through all these . Since it's a process , you will have to experience some of these
