I am stuck and don't know what to do next. I want to continue to pursue my dancing to become a pro one day. I was taking private lessons for about 5 years at a studio near where I live, but now my instructor has moved to another studio about an hour away. I want to continue to train and perform, I think I should find another dance studio to go to. It has gotten very expensive to take lessons, I want to be more serious about my dancing. What should I do next?

An instructor cannot teach you forever, try more instructors, then you will know what you want and what is best for you :)

What do mean by become a pro? Do you want to teach, compete, both? I think you need to clarify your goals and after 5 years of training you should start thinking about taking take your exams. However, you can teach without any formal papers and many 'pros' do. Do you have a partner? Most pros compete at some point in their career and to do that you need to practice and learn with a partner. Have you ever competed as an amateur? Every pro I know started as an amateur and worked their way up through the levels.
