Good relation with husband. Ego aside?

Hello, i want to know that how i will maintain good relation with my husband by keeping ego aside? Today, we fought because of my tone while talking to him in anger. He called me as usual when he got time from his office i was talking with my friend n i was not able to respond to his call. In a meanwhile, he called me twice. After that, when i recieve the call, i told him very angrily to wait for sometime. We both were so much angry. And now he is not talking to me. Even he told me to talk with him from now. I tried alot since morning to make him cool down n talk with me. But he is not even responding my messages n calls. Please help me what to do now... I really want my relationship to be healthy n want to restore love in my relation with him. Please help me.
