Hey guys, I need some advice. I'm in a pretty specific situation. A long term very close friend of mine (several years, long distance) and I are going on a one-week trip next month. We usually see each other a few times a year.

Few months ago she confessed her feelings for me and since then, the communication has been very suggestive, many times hinting at sex (usually she started the conversation in this direction, not me, but I absolutely played along). I'm not quite sure if I want to get into a relationship at the moment, however I'd definitely be down for sex, she's a 9/10.Since we started planning the trip like two weeks ago, she suddenly seemed to pull back, doesn't initiate sexual conversation and also doesn't play along when I initiate. I'm quite sure she would like sexy times, however she is kinda "blocked" at the moment and can't get in the mindset for it.Since she pulled back, I also stopped sexualizing the conversation (we talk every day), except for a few jokes here and there when they fit, however even then she doesn't really react and goes cold suddenly.I'm really confused what this might mean, if its just anxiety of seeing each other or maybe fantasizing while we can't see each other in a kind of "safe space" where nothing can really happen.

What do you guys think of the situation? Also, should I make any advances on the trip or should I just go with the flow and let her set the pace she's comfortable with?
