Is cracking my nose bad for it? (photos)

So you how sometimes you crack your kunuckles, i got into a similar habbit but for my nose and i cant stop. My family keeps on telling me that cracking my nose has made it bigger and crooked, they showed me pictures from a few years back, it was perfectly straight and thin, they said it was the ideal nose. Now its ugly, so ugly my mom even said it. I would like to know if they are right about the cause and what can i do to fix it. And in my opinion i look alot better without my nose like that pic.
