Power Dynamics

What are your thoughts on power dynamics in a relationship? People keep telling me it sounds like my on again off again boyfriend “has all the power” in our relationship. I understand why that’s a bad thing, but I just want to love him. I’d rather let him have the power, and love him the way he is. However, that means our rocky relationship is always on his terms. I just want to stay together and be there and love him, but instead we break up and then get back together (usually on his terms), and I end up sad a lot of the time. Do I need to try to take back my power? That feels inauthentic, but I also feel like my life is completely in his hands when I give him all the power.
