Well the one thing I can say is that it's a good thing you are not going to take this any further, OP. Cheating is wrong, so I salute you for realizing that and honoring your family commitment.
On the other hand, I think you would find that if you stayed completely out of this woman's line of vision, how quickly that 'love' with dissipate.....probably moreso on her end. I suspect that half of your reason for feeling this way for this other woman is discontent with your homelife. If she isn't experiencing the same thing, I can guarantee that in no time she will meet someone else she 'loves' just as much. Personally, I would recommend avoiding contact with her as much as possible. If you had the option to move someplace or location where you weren't working together, that would be ideal.
Bottom line is, the only way to move past it is to be firm and resolute about it. Don't discuss your feelings with her, don't get into any personal situations with her. Draw boundaries and stick to them. I can't give you anymore advice than that. I also think you need to re-examine your relationship with your wife. I know that if I found out my husband was saying or doing such things , it would rip my heart into a million pieces. Even if you haven't done anything physical, emotional cheating is just as devastating, and I'm speaking from experience here.
