I would re-pot it now, and then when the weather warms up it can go outside in the sunshine (but not scorching) for the summer - keep the compost a bit on the dry side, and keep an eye out for snails - they love them. Then in the autumn bring it in and put it on a warm light windowsill and wait.
I wouldn't split it - it's probably got three little plants in the pot to produce a plant that is balanced all around. splitting it would give you three lopsided plants.
Once you've re-potted it I'd stop feeding it for a while - the compost should have enough feed in it for a few months.
They're great to take cuttings from, so when it starts to get too big you can take some stems off and use them as cuttings - three to a pot, back to back so you get a well balanced pot
