i have to woman at work that seems to like me , we were sitting in the car on our way to work , me and her were sitting in the middle seats ( its a minivan ) , i was sitting at the door and we stopped because some of them wanted to buy water and cigarettes , i didnt need to so i just moved sideways so she can pass and she put her hand on my upper leg twice for support

When i was looking at some files she pressed her chest to my arm to look too , she was very close , she was shaking her leg like crazy and i grabbed her ankle to stop it and we both smiled at eachother

Are all of these sign that she likes me ? there is also one big problem , she has a boyfriend of 3 or 4 years
