Your wife will kill you or worse if you buy something that costs $1800 new that you will only use a couple of times a year
Oh... you have no idea. One DOES NOT piss off Mrs. McAllister. 
As to forms comments about the usefulness of the 70-200 2.8 IS, I disagree completely. I use that lens even for portraits at weddings and at receptions, I can sit in my little spot and take candids with no problems. I don't use flash hardly ever with that lens, as it's really fast and so sharp.
Yep, it works extremely well for you (and a gazillion others) but I can see it both ways.
These days, I'm just a lowly 2nd shooter whoring myself out to half dozen photographers when they need me. I've done my own weddings but actually like being #2. Less headaches and I sleep a lot better.
The only reason I'm even considering the 70-200 is because these guys are always up front and they almost always shoot with primes hopping around like freaking jack rabbits. Add me to the fray and it just doesn't feel right. Somebody needs to back up and just stay put or else one day, "Olga" the ex-shotput thrower from the '56 Olympics recently turned church hag will pummel one of us. (And rightfully so I might add!)
Were I on my own though... AND based on the liberal shooting conditions here I'd go for the faster primes and just do the zoom shuffle with not-so-nimble feet. The 70-200 still sounds appealing though... instant "creamy" portraits and instant wide without moving given the right conditions. I've also considered the 'fly-on-the-wall" approach to candids as well but to be honest, the venues are pretty small here.
The best way to resolve this with your wife, is to prove to her you don't want to spend the money right now, but save for it.
Naw... I'm just gonna dump her.
I kid! 
Actually, I think I'm going to hang low on this and just keep watching for the rumored new 70-200 slated for early next year with that high-falutin' hybrid IS. At the very least, one should see a ton of used IS 1's on the market.
God help me if it costs $2800 and I like it though. (Sterile, broke and single again)
Do you have a sister?
