Ok ... I actually think I found what I was looking for. I wanted an antivirus thing... so I download Avast! among its features, it gives you control as to which numbers and or text you want to be blocked. From my understanding ... you can choose whatever number you type in or from your contacts, and have those numbers blocked whenever you get text by them or called. You wont see it until you enter the password you set for it. So you can be very selective. You can even pick what days of the week you want those numbers blocked or you can block just numbers or just texts.
You can even choose to have those numbers blocked on outgoing calls! so if someone grabs your phone (like your sweetheart) lol and tries to dial a number, if its on your list...it won't dial unless they have the password! Even if the phone itself is unlocked...great! This way , your phone doesn't have to be locked down all the time and IF you leave it around nosy people, you don't have to worry!
Now Im looking at apps that change your number all together when you dial/text certain numbers/people you put on the list... like google voice.
WHY didn't I get a smartphone in my life sooner!!??? Im glad I waited for this one though!
