Welcome to PC, Dan24X. It sounds like you know that you are really interested in this girl.

Have you tried explaining to your parents that you really like her? It would also be a good idea to share why you think she is a great person. I believe you could also benefit from seeing a therapist in order to help you with communicating with your parents.

You might also trying asking this question over in the Relationships & Communication Forum. There is a great bunch of people over there that could relate to you and help you out.

Best Wishes!
