Tragic. Stay clear of her, don't initiate contact ever and be cordial and short when she eventually tries to reach out. Lying or not, she will eventually start looking for validation, justification, forgiveness and acceptance. As an injured party, (whether what she told you is true or not) you need to stand firm in your convictions or you slide into the same tar pit of her faults.

She has made it clear you aren't to be her savior, don't imagine yourself one.

Good luck with your future, seriously.
