Hey, you are not the only one with those kind of problems,the same thing happes with my partner as well.I'll tell you there is one way out find another partner if you feel you are being held back,however don't break up until you find someone to dance with already,or you can try to talk with her but it comes down to one thing is she made to become a dancer mentally,you need to find that out first and you need to know how far you want to take this dancing.Good luck!
