I always choke n i did it again??? helpp?

If you leave it too long She will just give up on you as well. I always found it helped thinking about something that made me really happy and confident. Don't be afraid of rejection! From what your saying she wants to be with you because she goes out in the car alone with you! Don't just blurt it out think about when and where to do it and then ask her, I'd suggest soon as possible tho!
