Husband says I don’t tell him what I think

My husband is always telling me I don’t tell him what I want and that I don’t tell him what I am thinking or feeling. But most of the time I don’t even know what I want, feel or think. I don’t feel like my own person and I always go off other people. How do I fix this about myself? I want to be my own person with thoughts, opinions, and wants. How do I communicate with him better without holding myself back?
