Removing my number as an option for iMessages?

I have an iPhone & my mom has an iPod & an iPhone. All of these devices were registered under the same apple ID. In both of our iMessage settings, my phone number is an option to be able to send & receive iMessages. On her phone my number is unchecked so she can't see my messages. But, I'm afraid she will check my number & then she can see my messages without my knowledge.So, I was wondering how can I make my number not an option for iMessage? Meaning how can I remove my number as an option for iMessage on all devices. Sorry if this doesn't make sense but please help?

What is the best iphone 5 case with extra battery, and cushion for dropping it?

I got a Mophie but I was wondering if there was any other brands that offered a screen protector, cushioning for dropping, waterproof if possible, and has the best battery extension. I saw Max Boost.
