<human>: Give me the gist of the text in a nutshell

Me 27, her 26. We've been dating for three years, about. 

She is Chinese. Her parents don't know about me - she's never introduced us. This is normal for their culture until she's pretty sure we'll get married. 

But, most of her friends don't really know, either. They suspect (why else would this guy be at all these social functions with her with no other real connection to her?), but she doesn't confirm. 

That alone has been kind of starting to wear on me. 

But also, I just get the feeling she likes having closeness with someone. She just does stuff that seems to indicate she's not really that into me. I mean, as the most obvious example, if I ask her what she likes about me, she either answers unseriously or it's about how the relationship makes her feel. 

However, on the other hand, she gets me a lot of gifts. A jacket, sweater, an iPad, a backpack, she brings me back souvenirs from vacations when she doesn't bring anyone else back anything. 

She also has a tendency to respond best when I start disengaging, which is something I don't really like. Suddenly becomes sweet, wants to start having more sex, stops constantly interrupting me, that sort of thing. 

I am her first everything - she has never even kissed someone else. I have an ordinary sexual past (handful of sexual partners, ltr's, etc.).

Part of me just wants to end it and be like, man, the chores of a having an actual, publicly-identified girlfriend are starting to pale in comparison to the toll this is taking on my ego, to be held, in some respects, at arm's length indedinitely. On the other hand, I am really attracted to her, and I know first relationships tend to be a little extreme because people have no experience to mitigate their impulses, which can cause some feelings of being taken for granted in the other party. 

Does anyone have any thoughts/advice?
<bot>: I frequently feel unloved by the gf due to how she treats the relationship, but at other times I see signs her heart is really in it. Help?
