RE: Red flags in a relationship

Last year I dated this guy, who doesn't call much, okay he said he doesn't like calls and that he prefers to chat, then I said It was fine, now even chatting sometimes, it takes him hours to reply to the chat, sometimes I will drop a message for him, he will take days to reply to that message then he will be like "he has a bad character that I'm not the only he is doing it to" that others are complaining about it as well.
