Seems to me that either he's not sure about her, or he has some issues going on in him that have nothing to do with her. Maaaaybe he has a bad relationship with his family himself, or his parents are closet conservatives who wouldn't accept a girl outside of their "zone"(no matter how nice and liberal they might look and sound). Maaaaybe there's something that he cannot share with her – or anyone else. Or…. yeah, maybe he simply doesn't want to get "stuck with" her (if this is the case, I sympathize and wish her all the best to move on).

God knows what though, when he's not talking. I'd say, ask him, because she should be able to, for having a relationship with him over a year, while being open-minded about every possibilities and the unknown to her – if he's not giving her a comprehensive answer, probably that's the time to make *the* decision.

By personal experience, I also think that being introduced to the family could mean not as much as she expects. Once a upon a time :P I got introduced to my ex's parents and that did give me a hallucination of a settling relationship. Turned out, he had introduced his parents to EVERY dates/gfs he had had in the past  – that's where he was coming from and perhaps naturally, meeting with their son's another girlfriend (who probably would pass by like everyone else they had got introduced to) wasn't a big deal to them. After learning that, I had a GOOD laugh about the "misunderstanding" I had. Good times! Oh, and yes, I passed by, like everyone else they have been introduced to by their son.

Even if we're introduced to every family member of our partners and cultivating the relationship for now – technically, there still could be "turning back". Why would some people end up with a divorce, even after having children together… Perhaps she needs to let go of the notion that meeting with family somehow confirms the relationship, or it might seal the deal or something.

All the best!
