Just be patient. She maybe holding to the rule about not dating anyone from work but feels a connection with you. Respect her wishes to keep things on a down-low at work.Otherwise, keep doing the things (outside work) that you two have been enjoying together.Maybe by her saying you make her nervous, she might be telling you to back off a bit.Maybe let things cool off for a little while, then surprise her (at home) with a delivery of flowers. Woman ALWAYS love flowers being delivered to them.Good Luck!
