If a guy never even mentions the idea of meeting his family or friends to you and you only ever see each other one on one, that could be a huge indicator that he just sees you as a hook-up. If it's been a while and they still never make an effort to include you in things like work events or family dinners, it shows they don't see you as their girlfriend. If he saw you as a potential girlfriend, he would definitely introduce you to his friends or his family, or at the very least, bring you out to group hangouts or parties to see how you mesh with his group. This has even become a dating trend in called pocketing, which happens when someone doesn't introduce you to their crew because they're hiding you away. A guy who wanted something more would ask to hang out in broad daylight too and go on fun dates, not just Netflix and chill at his place in the night-time. This is an actual problem that millennials face in the world of Tinder. Let's be honest, we've all dated a guy that we meet up with once in a blue moon but the majority of the relationship is contained to texting each other on the dreaded dating app.
