it is leaning most likely.. due to lack of properly intense light ... its called etoliation ...

imo.. your best bet is to propagate .. root.. the longest pieces ... and start a new more vigorous version of your old plant ...

and it is easiest to root small pieces.. not 4 foot long stalks ... just to be clear ...

i doubt repotting is going to do much of anything for you .. as it is now.. BUT.. once you cut off most of the plant for propagation... what is left should resprout.. and eventually a repotting might be good.. media does wear out over time... so replacing it never really hurts... i might do it at the same time as the haircut.. so by the time it gets over all the stress and starts to reprout.. you wont stress it again...

and to think.. you will be getting back 6 or 8 square feet of floor space in the bargain...

@ken_adrian Adrian MI cold Z5 I have propagated this plant a few times already. I just haven't given the momma a haircut...yet.

You could rotate the pot and lean it against the wall. If a pot is never rotated, the plant will lean toward the window. Aside from the lean, it's a great looking tree!

The plant is leaning because it doesn't get enough light. Plants allocate their energy in a strict order. Energy is first allocated to respiratory function, i.e. to maintenance of living tissues, then, to production of fine roots, followed by flower and seed/fruit production, then primary growth (extension of both roots and shoots), then secondary growth (thickening), and finally, the synthesis of defensive chemicals. You can see that the thickening that makes the stems strong is of low priority and only occurs when the plant is able to create more food/energy than it can use. When plants have excess energy the need a place to store it, and just like humans who take in more calories than they burn, plants roots/ branches/ stems get fatter as they create new cells to store the energy.

Now is the best time of the year to do heavy work on the plant. If it was mine, I'd cut the laid-over stems back to somewhere inside of an imaginary line straight up from the rim of the pot. Your plant will then back-bud behind (closer to the roots) the pruning cut and you will have fixed the laying over of the offending stems. There is very close to a 100% chance all will go well if you choose this route. The only thing you will need to be careful of is over-watering. With the main foliage mass separated from the roots, the plant will use water from the soil much more slowly. If you like, you can treat the tops as cuttings and root them to make new plants. If you need some guidance in making that happen, just ask, as you have options that will affect what type of plant you'll end up with (from the cuttings), and the cuttings will require some preparation to maximize chances of success.
