So we met in class two weeks ago and I’m traveling in his country now. I felt he liked me and added him on fb. Today he sent me the first text asking about my trip. I replied four hours later saying I enjoyed the trip, even sent a typical tourist pic of myself. But until now, which is about 5 hours still no answer. He’s online 2 hours ago but left me unread. What does he mean? Am I being too desperate for sending photo?
