Umm does she like me?

So this girl at work is from Spain and her and I have become fairly close working on projects together. She has a boyfriend she used to call me and we end up talking for long conversations mostly about work sprinkled in with some personal stuff. Now are meeting more and more frequently and we goofed around have fun together. We always call for an hour long meeting and often runs into two hours easy. The thing is is that we are always accidentally touching each other and bumping into each other like our legs will bump into each other and will leave it sending with her hands and arms. I can't tell if this is just her being friendly/European but I'm like dying to make a move and get physical. Lately she's been joke around about me buying her lunch she wants me to take her to lunch twice. I don't know what to think help!
