Maybe he is embarrassed of his family and how they act. Still not an excuse so I would simply ask him. If you are boyfriend and girlfriend... then now is the time to start asking difficult questions. Only way to grow as a couple.

... you've only been dating for a month or two though?
Some people just take more time to tell their family. I don't think I told any family members about my boyfriend until we'd been together for 2-3 months. That had nothing to do with the fact that he's Asian, they're just a bit weird about dating in general so I simply wanted to avoid any potential conflicts.
