You did not take that comment the wrong way! "Then I can plan my next escape," that was a shi**y thing for her to say after being away from her family for 12 days.
Be careful brother, this is a very touchy sitch.
Personally, I would have had her picked up via car service. That could be a real stressful ride back home.
STOP with the huge hug and kiss bit, that is what is going to get you in big trouble. If you are not careful, this could get real ugly tonight.
Pretend that you are picking up one of your buddies from the airport.
