My girlfriend recently wrapped her legs around another guys waist at a business meeting. He text her that he liked it, she replied I thought you would, he replied it turned him on!! She replied in shock to this and showed me the messages. She said she did this because he hadn't seen her in ages and for some reason picked her up and stepped forward. To prevent herself from falling she wrapped her legs round him...?? She says it's nothing and didn't mean anything to her. I feel sick thinking about it and question whether I can trust her. She couldn't see why I had a problem initially, but is now very sorry. What do you think..?
