I’m not sure what other options may be open to you. I would say whatever route you choose to go down, having a lawyer to guide you through it would be the best help for you. I wouldn’t want to go through the eviction process myself without a lawyer’s advice, God forbid you miss crossing a t or dotting an i and it resets you back to square one. And it sounds like you’re dealing with someone who would take full advantage of any missteps you may make. I feel bad for you and wish I could come up with some kind of silver bullet that would resolve the situation for you.
