Nah man. Who’s leading the interaction and the seduction here, you or her?
Regardless, the idea that either you or her is “trying less” is enough to give someone the ick. When she reflects on what happened before sex, it can come across as manipulative, like you wanted something, and you worked at it, but now you’re taking her for granted, and vice versa. There is enough evidence in this forum where men acted all stoic after having sex and they just got ghosted because the women felt promiscuous and slutty.
Either way, she is a plate now, so you have to show that the game isn’t over, that you actually want to keep things going without over investing.
Like I said, you can tell her you want to see her again and that you guys should plan something before she leaves. Then wait for her to initiate texting another day, spit a little game, and then meet up to do something fun. If anyone has other suggestions on what to do do you can hit it again I can wait to be corrected. I wouldn’t be too stressed about playing power games - it makes you look insecure.
