He doesn’t introduce you to his inner circle and/or family.
Anslem says: This one can go either way. For every guy that views women as trophies to show off to his buddies, there’s one that prefers spending quality time alone getting to know a woman he really likes. As for meeting family members, that’s a big step in any relationship, so unless you have an official title, don’t stress it. But beware the fella that appears to be purposely keeping you separated from his family and friends. That may mean he’s hiding something.
