Don't contact her again. You told her the truth about waltzing in whenever she felt like it and yet, you had no key to her place. Don't worry about it. This is one of the consequences of her actions and she needs to get use to you having boundaries. All mlcers are not happy when the locks are changed. Why? Because they no longer have control over the home and being allowed to come and go as they please.
Do not give her key or you will have defeated the purpose of this boundary.
She'll get over it and while doing so, she'll have to think about what you said.
Continue moving forward.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
