What to do about this woman? (Crush)?

I'm 26 and I work at a Circle K. A few months into my time there I began talking to and got to know this woman. She's 26 too, from the skeezy side of the town, likes the same pop culture as I do, we just pop. It all started where I'd be joking with coworkers and say some major disaster or inspection was caused by her and she'd laugh. Now we have a Monica and chandler like banter going all the time and there's serious sexual air between us, it's definitely palpable. If people see us talking they'll leave. It's gotten to the point where we're so comfortable and hot and bothered by each other that we just mention sex acts, like here's what a conversation sounds like:

Me: "handjobs" we both laugh

Her: "tossed salad" laugh even harder

Me: "*******" then she'd say "okay you win" we'd lean in and laugh it out.

Today I jokingly asked if she'd be my assistant And she screamed "OH YES!" And then when I said it was a joke and I had no need for one she laughed, bowed and went back to work. She's just my type too, redhead, pale skin, tall, intelligent. We both--thanks to the recession wound up driving former welding trucks and connect on that

The major problems is her family situation which is 3 kids from a previous marriage ( which I don't mind) and a boyfriend she's had for six months. I feel like fate set us up to be a power couple then someone made one decision which threw it off course causing me to get stuck in this alternate reality. Is there anything I can really do?
