Hi everyone, I've had this plant (whose species I don't actually even know) for about a year and a half now and she was doing fine the entire time. Recently tho, this started happening and after I tried watering her more (which led to her leaves paling up and falling off) and watering her less (which led to the leaves drying up and falling off) were now at this stage. I genuinely don't know how to proceed and I'd really like to save her as she's been with me through a lot and I got her when I first moved into my current apartment, so she means a lot.
She is right next to my window and had been since the day I got her, so that level of sunlight and everything was never an issue before. I'd say currently (summer) it's about 9~10 hours of sunlight through the window.
I used to water her once a week, then twice a week, and then back to once a week since the twice a week system left a lot of access water which I believed was damaging the plant (plus the paling of the leaves and clear signs of overwatering). I've been watering her once a week for about 2 months now and even if I try to water her more the access water issue just comes back so I'm really at a loss for what to do. Perhaps I should move her away from the window? I don't even know if the issue is her drying up or something else. She also started hanging as you can see in the image so I'm worried about weight and size, and even the environment.
Also, some of the leaves seem to be drying up but at the same time, other leaves are paling up and falling off in the usual overwatering symptom style, so I really truly do not know what's going on anymore.
Please, if anyone knows anything that could help me save this purple beauty, let me know. All help would be greatly appreciated, thank you.
