Hello, kime.

What I would do and what you will do might be very different but you did ask

You gave very little information so I am giving my opinion based on different types of relationships.

If this person is a friend: By the actions you describe the person is not a friend and I would no longer associate with him/her.

If the person is a family member: I would distance myself and possibly cut ties even tho' it's family.

If ther person is a spouse or significant other: I would tell that person I will no longer tolerate the abuse (control issues, threats and anger is emotional abuse).

The spouse/significant other needs help by a mental health professional and possibly couples counseling. If he/she refuses then it's time to cut your loses and walk away. In a relationship emotional abuse can transition to physical abuse.

Regardless of which senerio you question falls under what your describing is not a healthy relationship and for your well being it's best to protect yourself by getting that person out of your life.
