How do you know? Does he show it on his social media?
Sometimes on his SM, it does seem like he's lonely and very much more insecure than you would assume.
A few days ago, it seemed like he was talking to some girl and she lost interest. He proceeded to sort of vent some of his frustrations on SM, saying things like girls assume he's stuck up or a narcissist or whatever and that he doesn't want people to think that.
It does seem like he doesn't have a lot of friends though. Very ironic that he travels all over for photoshoots and whatever, but actually doesn't seem to have a support group.
Then again, everyone comes off on SM as a little needy to me lol
