Yes they will, they are terrible haha.
I don't think she is clueless I have pretty openly hit on her and she responded in the past with what seemed flirty to me. I would assume she isn't to dense to catch on considering she is pretty damn smart both street smart and IQ wise. It is all very weird and shitty to be honest. I've told myself over and over to stop talking to her, but I lack the will power to actually do so. Thing is it isn't like she doesn't know I'm gay, I have pretty openly told her sense the beginning that was the case.
I know she has issues with certain aspects of relationships because her mom died when she was 15, and then her dad died when she was 18 from being an alcoholic after her mom died because he couldn't cope with it. She one time told me she would never want to hurt me, and then a few weeks later she gave me a lecture one time about how she could never hurt someone she cared for and how people always get hurt in relationships. It all pretty much sucks.
