I have a crush on a girl and I don't know what to do.
If she's your type, why not pursue her?
I'm attracted to her as long as she's not totally flat
It's best to not worry about rejection. Putting yourself out there would be the best thing, that way you won't have to worry about what could have been.
I don't want to hear that she's just not interested in me.
I know you have a lot of anxious feelings towards this, but making the first step in putting yourself out there could turn out to be good. Just focus on that and I think it will help curb these anxieties.
