So we've been exchanging flirtatious glances with each other and her eyes always lights up when she sees me and talks to me. We instantly clicked! She always finds the right time to be around me. However there is this guy who she always hangs out with, who is her boyfriend. She is under the impression I don't know about that. I asked her about it and she still maintains the fact that she doesn't have a boyfriend. When we bump into each other with him in the picture, she always seems to ignore me. I'm really confused as to how to handle this situation.
