inflating a ballon violate Boyle's law

When a balloon is inflated ,the air inside the balloon has pressure greater than that of atmospheric pressure outside.And also density inside the balloon is greater than the density outside.
These molecules bang against the walls of the balloon inside and hence a force is produced at the inner walls which actually causes the increase in volume .
When we squeeze the inflated balloon the volume decreases and simultaneously pressure inside it increases.
Thus Boyle's law is not violated actually which says PV= constant or Pressure and volume are inversely proportional at constant temperature.

thank u so much
boyle's law is for definite mass but balloon mass is continuously increasing
