<human>: My brother and I grew up very close but I've been living overseas the last few years.  We've talked about him coming over for a visit (he's never been to Asia) for a long time and finally managed to both get 2 weeks off next spring.  We've been planning out a bike trip of Korea and hiking in Japan as well (we both like biking and have loved all things Japanese since we were kids) in that time frame.

Last summer he married his long time girlfriend, whom I know well, she's great, and they're very happy.  However, in his last email, he suddenly said "...**Wife and I are still looking forward to visiting** next spring..."

The thing is, in **all** the discussions about him visiting and our planning, before and after his wedding, his wife joining him on the trip has never been mentioned.  And while his wife is great, and I would be happy to go on a trip with them sometime, in this particular instance I have really mixed feelings because:

* A) I've been looking forward to this opportunity as a chance to catch up on bro-bonding time I've missed while being away.

* B) We've specifically planned to do a few different things because they're shared interests for my brother and myself, but those might not be things she's into (for instance, it sounds like she's not interested in the bike trip)

* C) I said I would pay all my brother's expenses because he is a student and it's not his fault I chose to live so far away, but now I'm facing either doubling what I have to fork out (or newlywed students having to foot the bill but I don't want them to have to shoulder that)

Is this just part of having married siblings?  Or newlywed siblings?  

And the more **important question:  is it possible for me to explain that I'd rather it was just my brother and I without offending him or his wife?**

Do you think it's better to talk to my brother about how I feel?  Or his wife directly?

Summarize the given text in a few sentences.
<bot>: My brother is coming to visit me in Asia, planned for long overdue bro time.  Suddenly his wife is tacked onto the plan.  Is there a diplomatic way to ask her to skip this trip?
