He won't add you on Facebook, red flag?

Anonymous
guy I had a casual thing with wouldn't add me on Facebook. he told me he doesn't use it anymore and how it gave him too much drama, bullsh*t. I looked at it and from what I could tell, there were old pictures of his ex up, but he did have a lot more friends on FB who are guys than girls, like he claimed.

and he still talks to his ex.

i don't think he's actually in a relationship with her but the way he talked about her made it seem like he isn't over her.

or could it be that she isn't really his ex? I mean, he's the one who brought up relationships, first asked me when my last one was, and then telling me he had a serious one that lasted a few years ago but it ended.

but I saw her name on his texting inbox (thanks large screen phones) so he's obviously still in touch with her.

i think he just doesn't want her seeing me and asking who I am. I know it means he doesn't take me seriously, but what else does it mean?
