<human>: Can you condense the text into a few key points?

I've been dating my GF for 1.5 years, and I've known my friend for about the same time (a little less). My friend and I have been a lot closer in the last few months. We have been on outings were we would just go for lunch together, movies, dinner, etc. and it was never a big deal. We have locked hands before and it's been fine.

Tonight it was. We decided to see a movie, and I put my arm around her (which has happened with no effect). This time our hands touched and we began holding hands, and then we almost kissed. We stopped and agreed that this wouldn't be a good idea and continued watching the movie (still with the arm and our hands held once after). 

My GF and I have actually been kinda distant. She's been very busy with university, extra curricular's, finding a job, etc.. We haven't seen each other in 2-3 weeks, even though she only lives in the town right beside me and actually goes to university in my town. I work far, and get home pretty late so seeing her during the week is hard. We usually see each other on weekends but she has been cancelling on my every weekend due to a large amount of work. 

This made me get really close to my friend, and what led up to today's events, and I'm not sure what to think about and how to approach it. We said we'd talk about later when we both had more time to think about it. I think I have feelings for her, but I'm not sure what to do.
