I'm scared we may not be compatible?

We've been together for a good year and I'm scared that even though he might be right for me, I may not be what he wants or doesn't even like me that much , I don't want to self destruct but it's terrifying. Our relationship is so good but I can feel myself pulling back because of fear of getting hurt. I'm scared that one day he'll wake up and realise that I'm not what he needs and that right there scares me to death. I like our relationship simply because our communication is good, we do the little things that matter and we're far more mature {emotionally and mentally} than most married couples and older folks (no disrespect ❤). I don't want to ruin a beautiful thing but this thought keeps coming back, what if I'm not "the one" but "the one" who helps him find his "hell yeah".

I don't carelessly throw powerful words around (words like I love you). I know without a doubt in my mind that he likes me but does he see himself loving me is the question. I've never been in love before but I'm just wondering.

Some may ask "why don't you talk to him cause your communication is so good?" I would but I need a 3rd person perspective.
