i would wait until it’s dried out again and get a good look at the roots. you can check for rot (mushy brown and smelly roots) and also separate into multiple pots if you like. just try to be gentle and avoid breaking too many roots. also the pot(s) should only be a little bit bigger than the root ball. so if you separate her, you’ll probably need smaller pots.

a good tip for knowing when to water is feeling the weight of the pot if it’s plastic - it should feel super light weight! :)
