My guy friend, after talking with me 2-3days at a stretch over text..( like two or three times a day) , suddenly stopped initiating contact. If I text him, he replies.but he dont ask any question in return or to be clear he dont continue the conversation like he used to do during our first time chats. He used to ask me questions & used to keep the conversation going earlier..But now he don't do this. Any idea why is this so??
