Viper GTS beat me to it! I've had a second job for the past 7 years. I make a decent buck, but I have lots of bills. I also have this problem with wanting a roof over my head, electricity and then there's that "food to eat" thing...... I like to live beyond my means and am willing to work for my toys.
Granted your situation is different, but we both need money! May I give my opinion on something? Good. Here they are, in no particular order and this is just my opinion and I'm not being mean.
1. Everyone knows that big, frilly foo-foo weddings are for two reasons only:
a) For the families of the bride and groom
b) To fufill all of the woman's little girl fantasies about a big wedding w/prince charming, long flowing gown, $44,000 in flowers, etc
What's missing here? Right, you. Your opinion is not counted here.
2. Don't let your fiance doom you both to a marriage doomed to fail because you started off $35K in debt because you (she) wanted a big, fancy wedding and a honeymoon in some exotic location. If you can't afford, you CAN'T AFFORD IT, PERIOD.
3. Back when my parents got married (1967) lots of couples were poor. Heck, most couples were poor. It was not uncommon to not have the honeymoon until you could afford it, say in a year or so. Bounce this idea off your fiancee. She'll prolly slap you, but you lose nothing by trying.
4. Your nuts are already in a vise. How do I know? You posted this, right?

Try to talk some sense into her. Do you really need the live, white horse drawn carriage to convey you from the curb to the church door? Etc, etc, etc.
Good luck. Call us from your buddies house when she locks you out. Seriously, good luck bud. Second job; here you come!
