You want to ask your crush out but how do you do it?

Tell her your feelings in a calm manner i.e. "I'm starting to develop feelings for you that go beyond friendship." No questions, just a statement. How she responds determines whether you pursue her further for a relationship or just stay friends. There are a lot of women out there, accept that it will take a lot of attempts to find the one that's just right. Worry less about failure and focus on being yourself; confidence is a very attractive trait to many girls.
