So you meet someone online, you talk throughout the day everyday for a while. Things seem great. You decide to have sex. He says he had a great time and asks you what you're doing the following week. Before he leaves you hug and kiss goodbye and he says he'll ttyl. The next day you hit him up like normal. He takes forever to respond and it's only one word when he does. Not a peep after that. Did you just get the shaft? Should you wait longer for him to start communicating like before? If yes, how long? Do you ask if it was a one time thing? What do you do?
