Using iMessage between iPhone and iPad?

I'm a user of the iPhone5 and iPad Mini with Retina Display. I'm having a bit of trouble with iMessage in that when I receive an iMessage on my phone it shows up on my iPad. I want to keep my phone number attached to iMessage on my iPad but is there a way for the iMessages on the iPad to show as read or opened if I get to it on my phone first? It's becoming tedious to open my iPad and see that I have a message when in reality I read it already 2 or 3 hours before from my phone. Will this also work vice versa?
