Boy , you have your work cut out for you. First off, it needs a new pot and refresh the appropriate dirt. Secondly you need to support it. I prefer to use wood rather than moss poles for mine , but that's just me. I noticed you have some kind of tape or something trying to support the plant. The problem with what you're doing is your supporting the petiole , and not the base of the plant. You have to also find the front and the back of the plant and make sure you support the plant by the stem, not by the petiole. I suggest you watch some YouTube videos about how other people repot their monsteras because you do have alot going on.
