The relationship ended, and if you ended it intellectually you'd should be happy she's gone, but we know these relationships can be traumatic even if we're glad they're over, this site wouldn't exist otherwise. Shift the focus entirely to you, see where you are and what you need, and then spend all your energy going after it. It's work to heal from trauma, but like anything else, the more effort something takes to achieve, the more valuable it is.
i hope i can someday forget about this traumatic experience of deception and manipulation
You won't forget, the emotional energy will just fade away until it doesn't matter anymore. In fact, once you do the work, you may look back and be grateful that you had the opportunity to learn the lessons you did. Take care of you!
