Advice from the old lady:
What’s the status now? Obviously you have oneitis...and obviously you were energized to see her contact you. This is the narcissist dynamic. You go radio silent. You remain radio silent. For the first few days or so she is thinking, great! I’m giving him the silent treatment...especially if you are still reaching out...this gives her fuel and validation. She thinks she holds all the cards...BUT...as you continue radio silence the tables turn in slow motion.
As the tables turn she realizes you might actually be gone, she might actually be replaceable, etc. So after a time she feels you have withdrawn your attention and she will start reaching out to see if she can still hook you.
You are best to remain NC. If you respond you validate her. I’m betting you guys are talking. My recent relationship had this dynamic from his side. He ALWAYS came back...then we’d start talking etc., and the whole cycle started again...
You need to decide what you want in your life. This has devolved into a toxic dynamic and trauma bond. Those bonds can be hard to break, especially if she’s attractive and the sex is hot.
But it’s unlikely to improve. You’re setting yourself up for more of the same unless you fundamentally develop strong frame, which means you DO NOT CARE if she leaves you or the relationship ends. I don’t think you have the chops to hold frame and quit being too nice right now based on what you’ve stated.
My guess is y’all are in touch and so forth...
