<human>: Could you distill the essence of the text into 1-3 sentences?

Right, get ready for a confusing ride. A few weeks ago I quit my job. As I was quitting my job, I thought fuck it, may as well ask this girl out who was also one of my colleagues. So I asked her out, and she said essentially 'Sorry but no, I'm seeing someone'. I then said fair enough, and left it at that.

Now, half a week later she messages me striking up friendly conversation. Friendly turns to flirty over the course of a couple of weeks, and eventually she is telling me that she's having problems with her boyfriend and she is developing feelings for me. She asks to meet on numerous occasions. She's also been sending me pretty sexual snapchats.

A few days ago she went pretty cold shoulder on me. I asked what was up, and basically she said she doesn't want to cheat on her boyfriend (which I would argue she's already done), and she thinks we should just be friends 'for now'. I told her that after everything, it wasn't fair that she continues to message me, as I had developed feelings for her.

As it stands, we are not talking. She removed me as a friend/follower on everything after getting pissed off at me for telling her that we shouldn't really be talking. We haven't spoken since last week and it's killing me. I can't get her out of my head.

I'm half thinking I should message her, but I'm also half thinking it's more trouble than it's worth, and that if anything did develop between us I would always be suspicious that she was sending other guys unfaithful messages, as she has done with me.

It's also fucked me up a bit because I'm not sure if she did actually have feelings for me, or if she was just keeping me as a backup incase her situation went tits up/keeping me for attention.

What should I do?
<bot>: Develop feelings for girl with complicated boyfriend situation which is very back and forth, I tell her we shouldn't talk, she takes this to the extreme and removes me on everything and avoids me. What should I do?
