To make a long story short:
Met hb8 over the summer at my internship. I'm 24 she is 20. We went on about 12 dates throughout two months, would sleep over at each others places, had sex every time we got together, held hand right outside the office (coworkers knew we were seeing each others). We would have deep conversations about life, I even planned a trip out of state for the two of us. During the trip she introduced me to her cousin and her cousin's bf that lived in the same area we were visiting. Late July, we both finished our internship but she left to study abroad in Guatemala for 9 months.
During our 3rd date I asked her to be my gf, to which she responded: "I'll answer that after you invite me to sleep over." I consequently invited her to sleep over, but never asked the question or brought it up again because I came to the conclusion that since she didn't answer the question or bring it back up she was not interested in a relationship.
We began keeping in touch just like we said, every other day sending a text. She would text me and tell me she couldn't stop thinking of me and that she missed me. But slowly as the first month has gone by, her responses seem to take longer and more days go by without me hearing from her.
*Finally I texted her yesterday and asked her to set up a skype date. She ignored the skype date and continued telling me about her experiences so far. I texted her the same question again to which she said that we could skype tomorrow, if she didn't "go out to a bar."
My question is:
I really like this girl and don't want to make a stupid mistake that i'll regret later.
A) Should I ask her on Skype whether she wants us to be committed on some level or how she feels about us?
B) Should I just forget about asking her out on Skype or revealing that I want a serious relationship with her, go out and find myself another girl and then in January go visit this girl in Guatemala and ask her out then in person?
