So i did something....

I deleted some dirty pictures off my mans phone. They didnt look like porn star photos they looked like photos some chicks he was messing with sent them to him. This would have been from before we got together 3 months ago... So it bugged me he still had pictures from those girls on his phone out of spite... Now i dont know how to tell him... Can someone give me some type of advice? Am i a bad girlfriend for this :/
