@PUNKEY,
I don't think this is the appropriate, or wisest time to bring up the costs of the wedding.
That's really premature. It's a time for rejoicing, not laying down ground rules when there are going to be all kinds of ideas for a wedding.
Also, the idea of "how are you going to support my daughter" is way out of date.
Well, since your daughter is getting her masters degree in economics, I'm pretty sure she's going to have an idea of how to manage funds.
I'm getting older than dirt, but even back in my 20's I would have bristled at the idea that my parents didn't know I could support myself.
It's not like the parents haven't know this guy for some time, and know what his plans for the future are.
