sure you make a point here that is quite true. but every kind of label or description of something can be misused by some people to describe others inaccurately. As you said there are people who are clingy per se but there is also a number of people who would call anyone that wants to hang out with them more than they'd like "clingy" As with everything you have to take into account the context of what is being said and you can't always take the word of someone else without using your own ability to discern whether something is true or based on that person's version of things.

With the person you describe it sounds like a person that I would not enjoy hanging out with in the first place. the trouble isn't you or anyone that want to hang out with them a lot, the problem is in that person being very selfish and self absorbed. I can tell just from the short descriptions that likely this person is quite self important and focused and quite possible very spoiled, bossy and in a nutshell, the type that fails to see others' needs and opinions as important as their own.
