"Haha. Thank you guys but James we have to go, we're running late." "Yeah but Bee," he lifted up the son of the couple that they asked for directions. "Have you SEEN THIS KID! He looks awesome!" He was shocked at how uninterested she was, jokingly he pulled a child like 'But Beeeee!' face. "He looks amazing, haha." They thanked them & left. She had to leave, she turned to him & said "Do you even know how good looking you are?"
Exclusivity, since you arent dating for the sake of it (there is actually purpose and longevity) why not have a coming out? why not just announce through your actions and the way you represent her that she is yours and vice versa? Exclusivity! so that people know its a relationship covenant between just two.
