How to find myself while in a relationship

So Im 19 and I was in a 2 year long relationship with my boyfriend when i was 16 turning 17. And we broke up over a year ago. Two months after we broke up i met my new boyfriend, whom I have been dating for a year. We live together and i love him more than anything. I realize though that i havent really been alone in a long time. I love my boyfriend and really want to be with him but ive lost my individuality in both these relationships. I dont know who I am. I do not want to break up with my boyfriend he is absolutely amazing. But I need to find myself in order to be happy. How can i do that while in a relationship. I feel constantly lost and i just need direction. Advice?
