Actually Phil, I'm fine with that. That was nice of you to offer to take her to the airport. That's something a friend would do. What you CAN'T do is probe her when you pick her up from the airport about what she did, who she was with, if she spent time with her ex-boyfriend, etc. When you pick her up, act like she just a buddy of yours that went away on a family trip and don't even think about what she did in your head, and don't ask outside of the general "did you have a good time, win any money?" type conversations. Remember, you guys are friends for now.
