How do I know of I'm too dedicated (not obsessed! 😇) with a fictional character?

I have most of the merch that looks like him/his clothes, jewelry etc
I have several posters and pics of him on my walls
My nieces has referred to him as uncle
My mom (jokingly) called him her son-in-law once
I have truedd to research wether or not it's possible to marry a fictional character


K, so when writing this I'm starting to think I know the answer, but I still wanna hear it from you guys.
