Is it bad if two people in a relationship need each other?

Usually its one person who is too needy or whatever and its seen as unhealthy. Is it the same/worse when the boyfriend and girlfriend both need each other to be happy? Or is that normal/okay?

My boyfriend has said the words “i need you” a lot both when we’re happy and when we are in bad terms. He says he needs me to be happy, he needs me because i make him a “better” man, or jus that he needs me in his life. Its pretty overwhelming sometimes but i love him so much. I need him too but i have never told him that because it scares me to let him know that. He probably does though.

So today i was upset with him and he said life isn't worth living if im not in it. Why is this making me freak out so much? Whats wrong with me? I love him and care about him but it makes me uncomfortable that someone feels this much about me. I feel like i should be happy but im not.
