Looks wilted, which can happen if there's not enough water OR so much water that the roots have been damaged by rot. The potting medium for jade should be highly porous so that you can water thoroughly at the appropriate intervals and be confidant that excess water will drain rapidly.

Is your potting soil a porous one....or mucky?

In addition to the soil issue, it looks like it is not getting enough light to me.

I'm not even sure what potting median I used. I did depot it a little back because it had outgrown its last pot (I know they're suppose to look too big for their pots and the pot kept falling over because the plant had gotten too large). Would it be harmful to repot it with a proper soil mix? As for the light, I rent and the windows are terribly insulated. When I had it near the window it kept droppin leaves and I figured it was due to the cold. I figured for the winter, it would be better to just give it a little less light rather than have it freeze for 4 months.

The potting mix needs to be replaced this Summer....but other than that, more light is the answer. This is exactly what underlit Jades look like.

I second the opinion that the plant is showing signs of etiolation from a lack of sufficient light.

Thanks for all the advice!! Even with the cold windows, do you think I should keep it in the window? Or wait til warmer weather?

As far as the cold windows go, I several jades sitting 6-12 inches from a patio door that doesn't seal very well. I'm in SD, so if your in southern MN we have similar weather. All of my jades survived the brutal cold sitting that close to the door. Now all of my plants should have been dry or mostly dry since the last time they were watered was before Christmas and everything is in small clay pots.

Depending on how warm you keep your place, I would try to find a spot next to the window that maybe it will get less cold air (i.e. if your windows slide horizontal to open, put the plant in the middle of the glass not near the opening or the seam) or if you have a little table you can put close to the window to set it on that would help too.

And then don't water it. That's the key, if it's going to be cold, it needs to be DRY!

Yes, cold and damp ='s death for jades..

Now it's time to give it some good sunlight in a window that will dry it out in the warm sun in time for the cooler night and do a transplant into a much better mix this summer as Josh say's....

I have my Jades almost all directly by the window, all winter, with only positive results from the bright light. And as I keep my place warm all the time, no problem with wet soil, as they dry out so quickly in the low humidity of a heated room.

Just had kind of the same problem- I forgot I had moved a Jade to a ? sunnier window when the temps went down to -24.Understand that in Minn. the temps have been twice that below. My Jade was definitely on the dry side so prob. why no problem.
Can you get some clear plastic to put over that window-might help keep some cold draft out and move the plant back a bit. They sell it pretty much everywhere-you use a hair dryer to tighten it up You might even like that you will be warmer-maybe your landlord will pay for it but I doubt it Take the plant away from window at night .No reason for it to be there then when it is even colder
Other alternative would be to put it under some kind of light-even a cheap fluorescent set-up and in the window when temps are reasonable.The idea is to get through the winter not necessarily to look great.
