Did you do ok?? You did great!!!! smile
You treated her with respect. You followed her lead without taking advantage. You were both N_A_T_U_R_A_L!! No fake, no expectation. She engaged the work and outside work kind of relationship you have. Hummm ????
Best of all, you both had a wonderful time..

Keep going with the flow.. I definitely think you two have something very special..
