<human>: My fiance and I have been together nearly 4 years and are finishing up our last year of college.  He proposed to me three weeks ago.  

My parents have been talking about taking him to India for a while now, and now that we're officially engaged they want him to come with us this August.  My dad's currently booking tickets for us all, and my fiance seems excited.

I, however, am a bit worried.  I've traveled with my fiance before, we went to Europe together for study abroad, and while he did grow a lot on his first international journey, I fear India may be too much for him.  We'd be staying with my grandparents.  There's no air conditioning, no cars, no shower, sometimes lizards crawl around on the bathroom floor.  There won't be familiar food (he has tried Indian food before, but it's definitely not a staple in his diet), and there will be a language barrier (my grandparents speak English, but with heavy accents and they likely won't understand him).  I'm also a bit worried as to how some members of the family will receive him.  None of them know I'm dating anyone, let alone engaged.  

I've warned my fiance about some of these things, but he still seems excited to go.  But part of me is really worried he won't be able to adjust.  I'm worried he'll think of us as backward, and I'm worried I'll think less of him for not blending in.  Are these irrational worries or are there steps I can take to fix them?

Can you give me the gist of the text in a nutshell?
<bot>: Parents have invited my white fiance on a trip to India with us.  He's not ready for the culture shock, but thinks he can handle it.
