Remark messing with writing confidence?

I've always loved writting and have always been told I'm good at it. I was writing a book and my boyfriend who also loves writting was insistent I show it to him even after I said I'd prefer not to bc I knew its the first draft. I ended up showing him the first chapter (at the time I had ten done). Once I sent itto him he sent pages worth of criticism and how it doesn't make sense things I should do instead and how I have to work on my writing. While I know that it was probably in good faith it really hurt and I can't get back into writing nor show him with any hobbies of value to me. Thoughts? What should I do? I have spoken to him and he has appoliges but it hasn't really helped.
