Her sister does not know we are dating (long story), and thought the guy she met at Burger King would be a good match for my girlfriend. So she gave him her number and so he could contact her. He looked her up on Facebook and sent her a friend request and they started chatting. After a week or so he asked her to meet him for lunch, and she went. She did not tell him about me in any way. I did not know about any of this until now.
She does not feel she did anything wrong and does not consider it a date.
She says people would agree with her. What do you guys think?
