Do you have an alliance that can back you up? Another option is to use a Truce agreement and build up your wall defenses so that once they do attack you they lose so many troops that its not worth it to keep attacking you. And if he's just too strong for that then all you can do is join and alliance that will protect you from bullies. And trust me, you shouldn't have a hard time finding people who will back you up against bullies. But expect to be bullied at some point. And there is no shame in starting over from scratch. I let my other game go after I learned from my mistakes.
