How do I know if she loves me?

Well, first of all, you need to decide wheather you love her or not. Not just like you MIGHT love her or you THINK, you love her. And as for knowing if she loves you, ask her.

If you don’t even know this person well enough to know whether or not they like you, you don’t with them. Some advice,> you need to learn the difference between a crush, infatuation and love. It will save you a lot of trouble and pain in the long run. You simply can NOT be ‘in love’ with someone you do not know. What do you ‘love’ about this person? Without taking the time to get to know someone, the only thing you love about them would be their looks, their reputation, or your own idealized version of what you imagine them to be. Lust, infatuation and a childish or immature crush, in that order. Sorry, but you need to get over this. You’re being unrealistic. When you really do fall in love, you’ll know it and you won’t have to ask anyone else. Neither will you feel so confused.
