Lol she came over by my desk today and I was working infront of a computer on headphones and completely ignoring her as she said hi to everyone else.

She walked up to me and stood for a few seconds beside me, I was ignoring her still, then she pushed the headphones off my head and into my lap, then walked off and turned around and looked at me with a smirk as she walked away.

Do you think this would indicate some attraction still after I failed the "I don't communicate with guys" shit test? If I want her, should I try again?

No no i mean "I dont communicate with guys" is a shit test not the hug
She's already slept with someone else from work and the guy banged her for a couple months then went back to his ex and married his ex.
She would still let him hug her and tease her at work and was laughing and giggling with him afterwards too (Where I'd imagine most women would be hurt by it)

Also when she found out I had slept with some other girl, the next day she came and sat down next to me and talked to me for an hour
(Sexual topics, she tested me several times to see if I would judge her for sleeping with me on a first date or for how many partners she has had (~20))
Mid conversation she said a joke that was terrible so I was like you having a stroke or something? you should get checked out. while laughing my ass off
And she's like "No, you should check me out" with f*** me eyes at me.

She shit tests a lot but looks just too damn good for me to give up on her. Literally gets hit on by all the men in the office/at clubs/whereever. ALL THE TIME.

What's my best shot at reattracting her after I failed her shit test (after passing many beforehand)?
