PLEASE BE GAY FOR ME 😭

So lately I've been so obsessed with this girl like I check all of her social media stuff all day and stare at her pics.. And we're actually good friends but I have the most intense crush on her. I literally feel like I'm in middle school again. So she knows that I really like her and she always says stuff like "your the only girl I would ever go gay for" and she talks about how I'm so bomb and stuff. It's very flattering. Only problem is she has a boyfriend and he treats her like shit (in my eyes) but she loves him. It's just annoying when she ask me for relationship advice because she should be mine! I respect there relationship so I don't talk about my feelings for her or anything but I really wish she would leave him and fuck w m or atleast someone who will treat her how she deserves to be treated... Should I leave her alone or just play it cool and continue to be friends??
