What should I do?

Check this out. I like this girl and she likes me back. What's the problem you ask, she lives about 30 minutes away from me. Whole nother school, and all that. We met at the church she goes to. I go to a diffrent church. I have her number,but I can't call her over the weekdays cuz my phone charges long distance. She doesn't have an e-mail,myspace,facebook,AIM,or nuttin like dat. My father is planning to get married to this lady from her church. But I still don't kno how it's gonna work. We've had a nice talk over the phone,and like I said,she does like me. Should I pursue this or look for more fish. Help me out.
