Alright, so here's what happened. I started a new job (Taco Bell, just until I graduate) A coworker and I started talking. About the time I began flirting with her, she started dating a guy. Well, we got to talking, and we just texted light, flirty convos, but out of nowhere she started texting me deep stuff about her life, all of her problems, etc. It's all fine, but I didn't know how to handle it, never had that thrown at me before, so I played the nice guy, I'm here for you AFC routine. So, I figured I got shoved deep into the friend zone, as she also began calling me her best friend, even tagging me in posts on FB using that term. However, she and her boyfriend, fiance I guess, even though she tells literally everyone that she has no intention of marrying her, he just went to tears when she initially turned him down, always fight, and she began flirting heavily with me, saying she wanted to be with me "eventually", and talked about cheating with me.
Well, we never got the chance to have sex, never was a right moment when we had a place to do it, but the "relationship" dynamic grew. Until I screwed it up... We talked and talked about it, but eventually they got on a phone plan together, and now they are living together in a shed (she got kicked out and he is broke, so a friend converted a large shed into a room for him.) Now, he reads her messages, they're always together (he can't afford a car, so she hauls him everywhere), and she doesn't want to talk about anything sexual or relationship in content.
Another thing is we argue nonstop. She just looks for little ways to piss me off or make me jealous, and when I return the favor on the jealousy part, she chews me out. Even playful negging that used to have us flirting now just pisses her off. So now I'm in the same "asshole" boat as her boyfriend. I was very close to getting her, but her living situation, and her sudden short temper and jealousy has me wondering if it's a lost cause. If not, what can I do to salvage the situation? Apparently her BF was bitching about her texting me too much today, and they got into a huge fight with her defending me, but IDK the whole story. How do I recover from the same stigma she places her boyfriend under?
