It surely does need a bigger pot, Glenn. Maybe about Feb or March would be a good time to do that, then pull up that window shade and give it as much light and warmth as you can to jump-start it for summer.
Also take a magnifying glass and look really closely at the backs of the leaves, and in the leaf axils. If you see tiny webs and little red mites, spray that puppy down thoroughly with soapy water. Put it in your shower or bathtub, use a spray bottle with 1/2tsp. dish soap to a quart of water, spray the whole plant, stems, soil, undersides of leaves, everywhere! Let it sit for a day, or overnight, then rinse it off with the shower head.
Mine always, ALWAYS, (pardon the shout) got spider mites when I brought them indoors. The mites just love warm, dry weather. If you can, put it in the shower, or the kitchen sink and spray it with plain water all over, once a week to prevent them.
But, don't worry, really Brugs are hard to kill. IF it does lose all its leaves, put it in a cool-ish place and just keep the soil barely moist until the weather improves. But still keep an eye on it for mites.
