Acquaintance. Sex. Cold. Ignore. ⇐ Pick Up

[Guest]

Gentlemen, I need your advice.
I'm 32 years old.
She is 22 years old. 7/10.
We met on a dating site. She started a correspondence. Big messages. The initiative to meet every day was on her part. We saw each other for a couple of hours and spent them having a pleasant conversation. Tactile contact. Everything is as it should be. Second meeting on my initiative. Kryshesnos (unusual place for a date). Kiss. We agreed on the next meeting at my home. We met for the third time. Sex all night and in the morning. The girl is in a pleasant shock, as he discovered new aspects for her and took sex to another level. After the meeting I took him home. I wrote a message saying how good I felt and wishing me a wonderful day. All three meetings took place within a week. The balance of importance was 70/30 in her favor (nice words, initiative, etc.), which is, in principle, normal at the beginning of communication.
Next, I want to increase my balance of importance. Mutual silence for almost two days (I waited for her to write). She wrote and shared how good she felt and how pleasantly melancholy she had been in the last few days after such a pleasantly emotional week.
Then we communicate via correspondence, the warmth is still felt, but the frequency of responses leaves much to be desired. To the mirror. Three days pass in this mode. There is no initiative for a meeting on her part. The response rate becomes even lower (a response every few hours). I put everything on the line and write her a message that I am now considering all such communication from the point of view of the future perspective, I feel that a coldness has appeared in our communication, and I am not used to being intrusive, besides, her imminent departure only makes it worse (the girl mentioned that after 3-4-5 weeks I would like to go somewhere for the winter, there are no exact dates, on the contrary, it’s as if there is a test going on from the series “make me stay,” so I would like to stop communicating (morally ready to stop communicating with OZhP, if everything doesn’t go according to my scenario). Reads instantly. She writes that she also noticed that we began to communicate less often, and thought that we both just needed to rethink the situation. That I am now cutting off communication without clarifying the circumstances and that it feels like I am simply leaking her.
This raises several questions.
1. What to do next? Should I somehow respond to her message or will I fall into the trap of starting to find out the circumstances and renewing contact? Or completely ignore it for a couple of days and offer to meet?
2. Did I do everything right in seduction or is my blurred eye not seeing something? Ready to answer all clarifying questions.
