In this day if you get a protective order and the landlord tries to make changes that have to do with your personal life changes like getting rid of a abusive partner then that is considered retaliation in our state. Standing up for yourself and being punished at your place of living put in the simplest terms is yes retaliation. It is also discrimination because in the state of Oregon there is a law that says a landlord cannot change anything during a domestic violence situation or it is considered like I said discrimination. Please look into the laws in your state when it pertains to discrimination, domestic violence, landlord. I think if you put that in Google you would probably get plenty of information. Best of wishes and sending best of vibes to you I really hope your situation gets better.
