It is not an easy to be in a situation such as this one. I mean you care about the person which is actually stopping you from reaching the true potential. But, what it really comes down to is do they care about you? That is in the end the question we all need to ask ourselves. In my personal opinion, the person who is stopping you to reach your goals really does not care about you. They just like the person they are using for their needs right now. You reaching your potential is not what is good for them. At least, this is how I make the distinction between real friends and fake ones. Real friends will never be in your way, but rather they will be with you on your way to reaching your potential. :)
