Actually, HE does talk about it often, to my DH... says things like, "I really need to look for a ring," "She is a good girl, and I know I won't find anyone better than her," but he ALSO just as often says how much he doesn't want to dip into his retirement fund to pay for the large cultural wedding her family expects.
I think she wants the HUGE wedding because without it, she will feel guilty. I don't think she is ready to be the first one to do things differently, as her sisters, cousins, etc., have all done the "right thing" and had HUGE weddings.
But I know he WILL retire at 45, and spending $50,000 on a wedding could set him back a few of years. He is just not willing to do that. BUT, he is READY to get married to her... not so much ready to spend $50,000 to do it.
