<human>: Can you give me a shortened version of the text?

We've been together for just over two years.  She's always had issues with the fact that I'm not Jewish (she's a Conservative, which by most people's standards equates to very religious), but after a couple months, she told most of her immediate family.  I get along well with them.  

She's always hidden our relationship from her maternal grandparents, as when her grandmother found out that her brother was seeing a black non-Jew, she had a stroke and was hospitalized.  I accepted her keeping silent to them on the grounds that endangering their health isn't worth it.

This weekend, though, she saw countless extended relatives - second cousins, great aunts and uncles - and when asked if she had a boyfriend, she said no, telling me that she wouldn't tell them because they're very Orthodox.  The paranoid part of me seizes on the fact that she got drunk and took shots with the bar tender, and wants to conflate them, but I want to believe that's just the hurt and frustration.  There's no history of cheating.

I'm hurt.  We've been together for two years.  It sounds like she's ashamed of me or embarrassed to be in a relationship with me.  I've told her all of this, and her response was to get mad and tell me that I "just didn't understand."

What do you all think?  Should I care?  Should I not?  And what should I do about it?
<bot>: Girlfriend of two years told her extended family she was single because they're religious Jews and I'm not Jewish.  How should I feel?
