is it something i’m doing ? or could be doing ?

me and this guy have been talking for almost three years we’ve been actually dating for a year and a half.. and he never post me (try not to make that a big deal bc social media isn’t everything but still a girl wants to be shown off sometimes) when texting we can never have a actual conversation its always dry and even when i see him it’s better but we don’t ever just talk.. like idk i feel like things should be different but then maybe i’m just expecting too much idk
