TO me it looks like a wisteria. Wisteria is not a tropical plant, and needs a period of dormancy during which the plant drops its leaves and waits for spring. Keeping this indoors is not a great idea, which you can also see on the weak leaves it has.
As spring is near, I would keep it where it is for now. In spring, move it outside. Make sure it gets plenty of light (Note: Being indoors makes it very light sensitive, so slowly move it into a more sunny spot; Start of with 2 weeks in the shade outside). Then just let it grow for the season. Once leaves drop in fall, look at pruning etc.
