Hey there, MelD!

Welcome to Maintainers -- stick around and keep posting -- you don't need to be at goal to post here, ya know.
A few thoughts on your plateau:

I have no idea why I am maintaing if I have a calorie deficit of at least 900 cals per day with eating less and exercise combined.
First of all, forget all the calculators that purport to tell you how many calories you need per day and how many you're burning and what kind of deficit you're creating. They're all averages AND they're all going to give you different numbers. Many of us here at Maintainers find them to be (often grossly) inaccurate. It can be incredibly frustrating to be expecting to lose or feel that you've EARNED 'X' pounds off per week and it doesn't happen. You start to feel like a failure or just throw in the towel since 'I did everything right and it doesn't work'.
Your body will lose at its own pace -- it doesn't care what some formula says that it should theoretically lose. Some weeks you might lose five pounds - some weeks zero. During the year that I was losing weight, I had a 17 pound month and a four pound month, back to back, without changing anything that I was doing.
I talked to a researcher who said that plateuas are frequently a result of cells being emptied out of fat and being filled with WATER. Until your body dumps the water, your weight will remain the same, although in reality you've lost the fat ... it just isn't showing up on the scale yet.
So ... patience!!! This is for the rest of your life, so what's the hurry? The weight WILL come off and you WILL reach your goal -- so what if it happens this month or not until next year?
In addition to patience, I do have a suggestion for a change that you can make -- add some resistance training to your exercise routine!

From what you described, your exercise is all cardio, which is great for calorie burning and a key component to any exercise program But now it's time to build some
muscle, both to boost your metabolism and to look lean and tight and defined when you reach your goal.
You see, muscle is the calorie burner in your body. Every pound of muscle that you have burns something like 20-25 calories per day. When you diet without doing weight/resistance training to maintain your muscle mass, studies show that up to half of the weight that you lose is muscle. Net result? Your metabolism slows down because you're burning fewer calories with your reduced muscle mass. And a slower metabolism can cause a weight loss stall.
The only way to increase your metabolism is to add some muscle with resistance training. But you won't get bulky, I promise!

Muscle is about 1/3 the size of fat, so losing fat and gaining muscle will give you a much smaller, tighter body. Check out
this picture of five pounds of fat vs. five pounds of muscle and you'll see the difference.
Have you ever lifted weights? Do you belong to a gym? Have any strength training videos and dumbbells at home? Hop on over to the Ladies Who Lift forum and check out the stickys there for some great ideas about starting with weights.
Stayed tuned and I'll bet you get some more good ideas from the gang.
