If no one filed for legal separation or divorce, then no one could make you sell your house let alone move out. You need a lawyer. Not talking to a friend who’s a lawyer. You need to hire a lawyer.

You keep saying you talk to a lawyer. That’s a friend who’s a lawyer, not your lawyer. It’s like if you need to make doctor appt but you’d say you already spoke to a doctor. He goes to my gym and we chatted on a treadmill. It’s not your doctor.

It sounds that you have nothing done legally yet. She moved out and lives elsewhere.

Are you expecting her to come back? Do you want her back? If not, time for legal actions. Take a bank loan to pay a lawyer. Either start legal actions or reconcile.living in a limbo is no good. And if she moved out, you need to change locks. She can’t just show up if she doesn’t live there
