I made someone fall in love with me and never talked to her
Why did you avoid her like that?
I was afraid that she'd reject me after knowing what I'm like.
I understand you're afraid of rejection, that's totally normal.  But that shouldn't drive you away from ever talking to a person who had feelings for you, especially after you made her fall in love with you.  That's bad for both of you!
What's the alternative?
You should not avoid her and see what she does. Maybe she won't reject you for who you are. You won't find it out unless you dated her.
