Background: I just moved into some dorms of a local college were I will be taking a class for the summer. This is my second night. I don't know many people who will be here over the summer so I figured it'd be perfect for practicing game.
The beginning: To my luck I am in the international dorms for the summer meaning lots of international girls who I can show the american life style to. I met a group of Brazilians and one cute girl ~7 (9 with the accent) who gave me some early ioi's Throughout the night as the group travels I play cocky funny and keep push/pulling her. It was pretty challenging with the language barrier but we managed. Night is ending and we're the last ones on the elevator after everyone else had left. I had the urge to just grab and kiss her spontaneously but decided it would be too aggressive. Door opens and she says "let me go first" in a flirty way (we had been talking about chivalry earlier, one of my filler sets) I respond with but of course. Once outside the elevator I decided it would be best to leave abruptly and causally because of cat-string theory. It worked excellently I said "well I'll see ya tomorrow!" The look on her face as she responded was priceless, She clearly had wished I stayed around.
Get back to my room to discover on Facebook that she has a boyfriend. Not the biggest challenge as it is long distance but it will definitely be very difficult.
Currently Today I got a facebook chat message from her sharing websites we had talked about (more IOIs) conversation continues to asking me to join the group for dinner (even more IOI's) I sit down first and she makes a special effort to sit in front of me so that we can talk.
Dinner goes so-so the language barrier was hard and her friends kept interrupting because they speak better English than her.
Dinner ends we go back to dorms and go our separate ways, 10 mins later she asks if im in the lounge ( I was ) and asked if I'd like company (chose me over her friends) even more IOIS!
Another guy from the hall comes join us and starts hitting on her quit hard. I let it go and talked with other people in the lounge while occasionally joining their conversation. She would make efforts to involve me in their conversations. (At one point while in conversation with the other guy she mentions the boyfriend which she still has yet to tell me about or bring up in conversation)
Eventually I suggest a phase shift to another lounge. I sit on a couch with her friend (girl ~5) and she sits on a chair. Her friend gets close to me as we have to share a cushion. At one point while talking with the 7/9 she makes some motion that suggest that her friend (5) and I should be a thing, it was very vague though.
Eventually the more attractive girl comes over to the couch and sits next to me pushing me between her and her less attractive friend (quite comfortably )Night continues with a few more IOI's and people begin to head off to bed. She stays around even though she is clearly tired. I decide to go with the abrupt end again and say I think I'm gonna go to bed. She says she has to finished something for her research and then she will. I say alright well good night then Ill see you tomorrow and leave.
Now: Its clear that she is interested in me and her pupils also dilate when we are talking (psych hint of attraction). She has yet to mention to BF to me. We will be living together for the summer in the same hall so I am not in any rush but I would like tips on how to escalate kino and attraction faster. I'm worried that cultural differences might make this very difficult
Side note: I have been invited to a frat party by a friend on campus in two days. I have to bring at least 2 girls though. I would like to suggest it to her and her friend but I can't bring the whole group and don't want to seem like an asshole at the same time. Any ideas on how I can go about suggesting this?
