Confidence issue in relationship Watch

I've been having conflicts with myself, I am a big advocate of being independent and being in control, however, since I've been in my serious relationship it has flipped. And after 6 months, I am the complete opposite. I feel like I need him support wise and as a friend. And I don't like it. I want to rely on myself more and be more emotionally stable within myself.
But, I don't want a break or want to leave him. The bond between is is extremely strong. I'm worried of turning into that big confident woman and becoming a female dog, because that is how I was in the past.
