(Long!) How to proceed from here?

I got myself in a weird predicament and am unexperienced in that regard aswell. Hope you can help me shed some light into my matter.

I know a Girl since about 2 years. She was introduced to our friendsgroup via a friend who was dating her for a short time. We never hung out and only talked barely werent interested at all and just viewed each other as friends but here comes the big but.

A month ago we talked about how we want to travel and this lead to us spontaniously booking a group trip for 15 days. During that trip, we had to share a room and sometimes a bed bec we were accidentally regestried as couple but no one of us really minded.

During that trip she meet a boy and they were kinda pushed by the others and me aswell, I was pretty supportive and left them alone when I could. Then a lot of weird stuff happend. That one night she and that Boy left the group earlier while drunk and everyone was sure they would make out. When I got back home to our shared room much later she was very quiet staring at the ceiling. When I asked whats up she told me that he missed his chance to kiss her and we somehow started to have a deep talk about relationships/dating and how tired we are from the dating scene and all that. Went out again and talked for some more deep into the night.

Now I still viewed her as friend 100% it was just that nice to be able to be that vulnerable to someone again.

The next night the same thing between her and the boy happend again. Flirting, getting drunk and leaving early. This time when I got home late she was still awake and alone aswell but kept staring at me weird and told me she ended this short thing with that boy. When I asked her if she got something on her mind she told me she can't tell me and I left it at that and went to sleep.

Then 2 days later during our second last stay of the Trip, she started dropping hints hard that she wants to cuddle, took me some time but I eventually asked if she wants to come over to my side which she did.
