Search Results: flirting with a boy

So I suspect a friend (female) of mine is interested in another (male) friend of mine. She has a a boyfriend (of 7yrs) and they live together. She was previously interested in him before she got her boyfriend and has flirted with him at parties etc over the years (but nothing serious).

Now there's been a couple of trips (cabin) with the closest friends over the last year that was planned but never happened. Previously to these two trips the girl had not been interested in joining. I asked her this time beforehand and she made all kinds of excuses and was clearly not interested. Then a day later I told her that I and the boy (she might be interested in) had talked about the sleeping arrangements and that they were decided and asked again if she wanted to join. She and him were to share a room and bed alone (this wasn't a set up). Then all of a sudden she changed her tone becoming less dismissive and using laughing emojis a lot.

She then asked if all the boys (there were 2 others) were certain to join and I said yes. I asked if she was ok with these arrangements and said "yeah sure as long as he doesn't snore (and plenty of laughing emojis joking it away)". She went from not keen to super keen. I then asked if she wanted her boyfriend to join and then she said he couldn't and said what a weird thing to ask (using laughing emojis nervously). We were supposed to be 6, and then I said that two of them were uncertain, and she asked what would happen if they didn't join. I said i dunno and asked her opinion. She then said "I can join you three (all boys) if you dont mind? *laughing emojis*.

Later this year there was another trip, and similarly she was not so keen, but I said we could just have the same sleeping arrangements as earlier and she became giddy and wanted to join even tho we would just be the four of us again. She then noted that it was NOT because of who were joining..

The trips didn't happen after all, but the question is what do you think she wants and what would've happened?
