Never let anyone hinder your growth, never let anyone be the reason why you choose to grow. If you know that you can achieve more, or that there is a better version of yourself that you have yet to unlock, go for it. The only person that would limit your personal growth is yourself, therefore if you want to achieve something you have to be the sole person that initiates and strives for it. Your partner deserves the best, and you should first become the best.
