Hey RF! I am so sorry about the money situation. Hang in there. Things will get better as you guys get more established. It just takes time. If you need to get a 2nd job go for it. I used to make scads of money waitressing when I was in college. Even after college, when I first had a teaching job, I would waitress on weekends. Teachers pay was not that great 20 years ago. I could work every Fri. night and Sat. night make almost as much in tips in a month as my monthly paycheck after taxes for being a teacher. If you can be really nice to people, quick with drinks and refills, make sure orders are correct when coming out of the kitchen and a little bit funny and personable, waitressing is an awesome way to make money. I think now it is a bit harder to make money waitressing as more people pay with credit card. Back then, you just pocket your cash tips, and not report them. At first I was reporting all my tips and my manager set me down and said, "Uh, honey only report $x.XX amount of your tips." I can't even remember why, but there was some sort of reason.
Then I thought when I married my DH that money would no longer be an issue. He was 30, and I thought well establised in the community, had a a good job, etc. I just didn't know why he was living with his parents.

Well, he had sunk every penny he had and was mortgaged to the hilt in a subdisvision development. I remember telling him I owed $300 on my credit card and I wanted to go back to waitressing before we got married so I could pay it off. He just laughed and said, "Honey, that's nothing." And then told me what his land mortgage was and his street development mortgage. Holy cow! We were so deep in debt, I never thought we would work our way out. It was unimaginable to me to owe that amount of money. 17 years later the good news is that we came out way ahead on that deal. It took about 3 years for us to break even (which was when we bought a house) and it was after our son was born (4 years later) that we really started to see a return on that investment.
The best advice I can give you as a newlywed is stay out of debt. There are going to be expenses that you can't avoid like a car breaking down or a flat tire, etc. So there may be things like that that you have to charge just to stay afloat. Just have a positive attitude and know that if you both work hard and save, you can get ahead. It can also be fun to be creative with looking for ways to have fun without spending money.
Hang in there, things will get better. It just takes time and hard work. If you are creative and have a positive attitude, you will look back at these times as some of the best times of your life. It may be hard to see it now, but trust me. Just stay positive.
Here are some of our favorite newly married, money saving, ideas:
1. Eat beans. They are way cheap, then later in the evening you can sing: Beans, Beans, Good for the heart, the more you eat the more you ______, well I am sure you know the song. We are pretty silly, and are easily entertained.
2. Have "Lady and the Tramp" cheap spaghetti by candle light night at home, once a week. I once caught myself on fire from our candles, which to this day my DH refers to me as his "smokin' hot" wife.
3. "Rent" movies from the public library. Hey, it's free.
4. Take long walks, go to the park together. Pack a picnic lunch. Feed the birds with your stale, moldy bread.
5. My DH would say his favorite newlywed activity is free.
I know there are a lot more but these are just some of the ones that come to mind.
I bet some of the other girls on here have some great ways to save money and have fun. I think most everyone has been there at one time or another.
