Spyware?

Is it possible for a third party to jail break my phone without me knowing about it? And if so is there a way to detect that? Many thanks for your help.

I am going through this right now. I feel like I am losing my mind and my ex is probably watching me type this. He is the devil...

Backup your phone and factory restore to new . Don't restore with a backup you'll just put it back . Change your iCloud password . I made new I'd and password .

Matt my boyfriend pulled up my deleted texts and my phone is not jail broke
