My wallpaper is decaying Really quickly?

Ok so, I noticed That my wallpaper was decaying and was getting really wrinkly and i thought my wallpaper was getting old, So I didn't mind it because i thought no one would notice, but the next day the wrinkles Had grown even more and the wallpaper was tearing up! I told my mom and she just told me it was getting old. However the wallpaper is decaying unusually quick, every once in a while a flake of wallpaper would land on me while i'm doing something in my room! And sometimes those flakes are the size of an iphone! Right now My Wallpaper is looks really messy and there are flakes all over the floor, i don't know if something died or anything like that to make the wallpaper decay, but my wallpaper is going quick! Please tell me how to stop this or if any of you are having this problem too!

I can think of only two reasons for this happening. The installer used a bad wallpaper adhesive that isn't holding up or there's a dampness in the walls or the air in your room and it's causing the wallpaper to wrinkle up and fall from the walls. You could try a dehumidifier to get rid of dampness in the air and the wrinkles might actually flatten out. Honestly, I doubt it but it's worth a try.

Another factor is that the walls were not primed before the paper was applied so the adhesive never stuck well. If you can just grab a corner of the wallpaper and it easily lifts off, that is probably what's happened. The paper would all have to be reapplied or just removed, the walls washed of adhesive, primed, and then painted instead. Lots of work but if the paper can't be saved, what else could you do?
