<human>: We started seeing each other in the Fall of 2009. I 21f, haven't yet met his 24m parents or anyone in his family. They live roughly thirty minutes away.

It also took over six months and some prodding to meet his best friend, who at the time lived in the apartment under his. There have also been numerous times when he went to see a sibling while I was with him to "drop something off" or some other innocent activity and instead of bringing me along, he left me alone to wait in his apartment.

I know how he explains his actions, but I'm interested in what theories you men of Reddit have to offer.

Can you condense the text into a few key points?
<bot>: He still won't bring me home to meet the family after over 3 years. Why would a guy act like this?
