My boyfriend and I have been dating for almost one month, in that month we have hung out a lot, maybe 4 to 5 hours at a time 3 to 5 days a week. We've got really close fast. I never asked him for his social media but I saw that he has a facebook. I dont understand why he wouldn't want to tell me he has one. He also will talk to his friends for hours apparently, but we haven't talked on the phone once. We only text. Should I be worried?
