Quick answer
You can seek safety help without a visible injury. Eligibility for a legal order requires local assessment of the conduct and circumstances.
Do now
Record specific threats and controlling conduct if safe. Contact an advocate using a safer channel. Ask the local court or lawyer about civil protection and related housing, family, or criminal options.
Watch for
Do not assume every harmful interaction meets the legal definition of a particular offense, or that lack of bruises means no legal remedy.
