Direct your attentions elsewhere.
Mixing business and romance is in itself very difficult to pull off without a massive explosion of drama that hurts everyone involved and spares shrapnel for those who just happen to be nearby. Add in the employer/employee dynamic, and we're talking at best a ton of work to try (and usually fail) to mitigate the power imbalance, and at worst a sexual harassment lawsuit.
You've described yourself as someone who finds it difficult to interact with others. You find yourself falling for someone in a situation where you couldn't help but interact with her. In other words, your hindbrain is screaming "take the easy way out!".
I get it... our society makes the location, selection, and courting of mates difficult and extremely high-risk for heterosexual males. It's dysfunctional, and it needs to stop. Women are trained almost from birth in a set of behaviors and expectations that hamstring you at every turn, and yet most feel powerless in a situation that can be just as frustrating for them.
Learn to be more effective in finding and wooing mates in a situation where you aren't mixing different relationship types, and do your best to step out of the expected patterns. When you aren't reacting to a self-imposed scarcity, passing attractions won't be such a big deal, they'll just pass.

P.S. -- Yes, I know I just made all of that sound far easier that it is. It's not easy, but it does work if you go about it right. I know this because I tend to send my male friends and partners into the world far more capable at selecting and wooing interesting women than they were when I found them. It's just another skill to learn.
