I have, at this moment, an obsession with someone else.  she shows me a lot of red flags, she's even in a relationship that doesn't make her happy.  she told me that she is attracted to me but that she can't be with me.  she likes my attention and i think she uses me for ego.  Me instead of pulling away, I insisted on having something together, I think a lot about her and the possibility of having a serious relationship.  what do I do?

Edit: I confronted her, saying everything I think, that she was using me to feed her ego.  she replied that she didn't know how to deal with the situation and that she would have to block me..
