Hello, thank you for the question.
When you're on title, you're as much an owner as she is, and she doesn't have any authority to throw you out.
However, you run the risk of upping the ante. If she wants to play dirty, she'll take your papers that are hard to replace, or call the police to say you assaulted her.
It might be time to have a reasonable conversation. Say that if it's over then it's time to separate your lives. She earns more and if she wants the house she should buy out your share. See if you can keep it civil until there's a plan and you have a place to go.
In the meantime, keep your unique papers in a safe place, like tax returns and ID and insurance policies, change the PIN on your bank accounts and credit cards, change the passwords on your email and online banking, maybe start getting your mail delivered elsewhere. Better safe than sorry.
Does that make sense? I'll await your question or comment if any. If I've answered you may I please have a positive service rating?
