Hello guys, so I recently remembered a girl that I met 3 years ago. It was at a dinner and she was sitting next to me. The unexperienced fool that I was (17/18 y/o), I didn't really know how to do all those gentlemen stuff like pulling out the chair for her so she can sit and stuff like that. Thing was that this was a dinner with a lot of people and we were about 10 people at that table and back then I was into another girl at that table. But sitting order was random so I talked a little bit with that girl next to me and she was super nice. She had the same interests as me and was very good looking. But since I really was into that other girl I wasn't taking that chance (stupid me). We never saw each other again. So after 3 years now I suddenly remembered her and thought I might text her on facebook. I did some research and found out her name (through the help of other friends from that evening) and it turned out that she has sent me a friend request back then which I never replied to. So I replied now and asked her if she was that girl from that evening at which I embarrassed my self with my not gentleman-like behaviour. I sent the text at saturday evening and she recieved it but she never opened the chat. Now I don't know how to handle this situation. Should I text her again in case she didn't see it? Or should I just maybe wait longer and wait if she opens the chat and read what I wrote? Please help
