He is not letting me use facebook! Should I delete it?

Just because english is my second language and all my friends are writing things there on my language and he does not understand it. Anyway, I never had it. We had a huge fight and I created one. Now I have it. Should I delete it? I know he would be mad if he knew. I dont really need it that much. Its just a good way for me to stay in touch with my friends that are very far away from me. And I dont want to keep it in secret from him. We trust each other and it will just creat a problem.
