Just to put things into context: Both I and the girl in question are in a foreign country, Australia, on Working Holiday Visa's. All this takes place in a quiet backpackers hostel in Melbourne. She's German and I'm sort of a third culture kid but from the UK originally. We're both 20 and I lack experience for my age with this sort of thing so if this comes across as very trivial I apologize I just want to learn as much as I can.
Basically I met this girl, pretty, in the general lounge area by ourselves and nothing ever escalated above friend ship status. We spoke for a few hours and seemed to hit it of nicely. We met and spoke on several occasions and it was all very nice. Her English is fluent but she still finds me hard to understand because I tend to use big words but we often had a laugh about that. She even commented and picked up on the notion that I'm smart especially compared to some of the other guys here. I don't mean to put them down since they are able to make her laugh and feel comfortable more easily and since whilst I'm kind of awkward and tend to talk about deeper things.
I bought her a few drinks on a couple of occasions and everything remains cool until one night there's an absolute piss up at the place we're staying and I do love to drink but things got out of control that night. It started off as a fun party we talked a lot (her and I) and then I completely blacked out. Next day everyone acts like nothing happened but I'm informed by a friend that at one point I tried to kiss her. I don't really know what else happened or if she reciprocated but as far as I know she just turned her head and was pretty wasted herself.
Anyways things seemed to be fine afterwards and I just acted like everything was normal. I couldn't find many chances to spend time with her over the next week due to work and she made friends with other guys and they got to go out for her last weekend which I missed out on because I worked the night shift. During this time though I asked for her number and exchanged a few texts. I was also lucky enough to have her in my room and we chatted but outside of that she seemed to prefer the company of others even though I made a point to apologize for the nights events and joked about it. Eventually she leaves and we hug goodbye and I find out she's going to be back in this city in a couple of months so I figured I could keep in touch and stay friends through text and such, maybe get another shot.
So I send a friend request on Facebook which is never accepted (she was friends with everyone else already). I give it a few days and send a text of the "How's it going?" variety with no reply. I give it another couple days and send another. Eventually she got back to me stating that she was sorry but she wasn't interested in staying in contact and that she had a boyfriend and made a note to wish me the best. This really got to me because she's on her phone half the time communicating with people she's met on her travels and now I'm an exception. I sent a lengthy self depreciating apology for making her uncomfortable saying I only ever wanted to be friends and wouldn't mind checking in on her every now and then to which I received no reply to date ( 8 days later).
A positive interpretation of this would be that she saw me as a prospect and felt guilty due to the boyfriend but being a cynic I can't help but think that she found me distasteful and tried to get me out of her life in the nicest way possible, boyfriend perhaps being made up. What I'm asking is whether or not it's kind of rude to blatantly say she didn't want to stay in touch at all, I mean we exchanged numbers and texted and such while she was here, she even sent me lengthy texts about how her day was going and I never made a pass at her again. Also is there any way I can salvage this? I got her on BBM, even after her message and the lack of a response to my apology could I still come back with a sort of "haven't spoken in a while, thought I'd drop you a line" kind of thing. I really would like another shot just to be friends.
