I've had a very pronounced crush on my best friend for months now. We flirt constantly and are pretty much the backbone of each other's emotional support and people around us are constantly telling both of us that we should start dating (happened to me yesterday, got rather awkward). The only twist is that she already has a boyfriend who she's been with for a little over a year but they've broken up and gotten back together multiple times. Their relationship seems very unstable and the guy seems like a total douche and whines about everything, so I just stay really close to her and we have fun.
She asked me today if I wanted to share an apartment with her next month. A worthy consideration but I have to move out of state for school so it'd be incompatible. I'm welcome to stay at her place whenever I'm in the St. Louis area though, which should be rather frequently since I'm just one state over and have ties here.
