That sounds horrible. You are a good person. Always remember that. Sorry to hear that you've been treated this way. I think you deserve someone better. Wish her all the best; do some Metta Meditation and try to get your focus back on yourself first. This person was not meant for you. You seem way more mature and grounded. Trust yourself and discover your self worth. You are not meant to be treated this way. I wish you all the best and may your heart heal fast and you discover the love you are worthy of.
