See, but its not. Accepting someone beat you or battered you does not mean you must allow it to reoccur, or remain in a similar relationship with them. By all means, the nature of that relationship should obviously change.

It means you accept that they did those things, and that they may do those things again, and support their personal progress and improvement in life.

You never need to grant someone power over you. Accepting them in spite of their past acts is a way of taking that power back for yourself, and making it your choice when to grant it or give it in the future, if ever.
