My friends roommate has a bf, but we started talking and cuddling once, like a month ago and we are doing the same very frequently now. I kiss her on the cheek, but she never let's me to kiss on the lips. We watch movies together, cuddle, she always flirts with me, we get into deep talks, but not more than that. She is usually very attention seeking whenever there is people around. Her bf seems a bit aloof and my friends are thinking that she is using me for emotional support when she is lonely and the bf for the physical part. However I move forward, she tries to stop at some point of time, but still flirts with me and everything the next day. She never initiates anything like texting me to meet up, but whenever i am around and initiate things with her, she gets along until point. It's like the window is never closing, but I has a limitation. What am I supposed to do here?
