what is her intention?

(me 23M, her 25F) I know, don't shit where you eat and everything, yes, it's why I haven't made a move. But I've been at this job for a while, and a few months ago started to really like this coworker. I guess the attraction grew to the point where one of my coworkers thought we were probably fucking low-key. We weren't. She was friendly, open suggestive body language (had my legs spread out, she'd stand near), she was touchy, would call me by my first name (we don't do that at our job), bought Starbucks one time, and asked why I didn't ask her to go grocery shopping (considering I didn't have a car yet and was new to the team). But I didn't reciprocate, so she moved on and later started bringing a dude to the workplace. He looks similar to me lol, but always looked at me with envy and disdain, as if he knew our workplace tendency. He brought food one day she didn't finish, he looked upset, and left. They married a few months later, and she's pregnant. She always talks about her pregnancy, but time to time she looks a bit sad. I flirt, and get a ton of attention from other women. She jokingly asked me if she should pay 500 for a stroller today, I joked back, why not? Talked about her dog one day, using double meanings, referring to the fact that she "wanted him in, now not anymore" and the fact that he's "bored" and has "separation anxiety." Etc And now, after so much time of us back and forth, I find I can't stop thinking about her, I'm someone that's extremely rational and thinks everything down to the T, never letting my emotions take any place, how can it be that over all the interesting women I meet and see day in day out, she's the one I can't stop thinking about? As if, maybe, to induce guilt for not taking her in. Part of me maybe says I'm overthinking because she's so subtle, or maybe that's because her game is really that good, we're both brilliant people. She has her days, she's bitchy, tender, talkative, petty, sometimes quiet, but lovely all around. I love her.
