I just set parental controls on my bf's pc
Why would you put parental controls on his app?
I want to control what he's installing on his PC.
You shouldn't be trying to control someones life like that. It's not only immoral but very wrong to try and control someone like that.
I'm his ex and I can do whatever I want.
Trying to control a partner in this way is not something that is going to create a lasting relationship. Eventually he will just find someone who allows him to have more freedom if he feels too restricted with you.
