Casually seeing this guy for quite a few months now. We sleep together and talk, that's about it. However, now he's being less consistent with seeing me, when he wanted to see me literally every week before. Recently when I saw him he asked for my FB on his phone so I told him which profile was mine and he was like ah okay there you are. Then he played his soundcloud and invited me to listen to what he posts and what not. Yet, he never added me on fb…What's that all about?
