Todd sounds like a classic bridezilla. He's so caught up in his own special moment, that if fails to occur to him that 1) Nobody else cares as much as he does 2) Other people have special moments too and 3) His behaviour is way over the top compared to how everyone else celebrates things like birthdays and engagements.
I predict an engagement party, a bridal shower, a stag night, a hen night, a Jack and Jill, and a full week of wedding festivities, plus a post wedding video show and rehash. At each of these events, the participants will be expected to pay for themselves, and chip in for the bride and/or groom, and possibly buy lottery tickets. The multi-hour video tribute to their relationship will show up for at least three-quarters of the events, including the wedding receptions, with video from each of the previous stages tossed in, so that each successive watching is longer.
Personally, I'm looking forward to the stories, but I feel sympathy for the OP. I think that she and her friends will need to collectively develop iron spines, and figure out how to tactfully explain to Jenny that they are happy for her, but that her fiance's demands are driving them away.
