Relationships always benefit from strength and thoughtful honesty.
You're hesitating and not moving forward. Why is that? You'll have to give yourself an honest evaluation of the situation, including your own mental or psychological state. Try looking at it this way: if you don't do anything, and just choose to keep moving along in the same direction, what is the best you could hope for? Now, is that going to be good enough for you or do you want more?
Once you have tackled a particular task or skill successfully and can do it with one hand tied behind your back, look for a way to improve upon your success. Never stop looking for ways to improve or better yourself or your work.
