My step sis and I have been spending a lot of time together lately and I find myself thinking about her as a girlfriend. She hates when I go out with my friends and plays love songs whenever I'm around. Maybe I am getting mixed signals. I am tempted to tell her how I feel, but I don't want things to be awkward between us. I take her to the bus stop every morning and walk her home every afternoon. It is obviously not exactly "normal", but I would like to know what I should do. Please help.
