Forum:Breaking up in MASS EFFECT 2

Hello, I have a little question. I am playing Mass Effect 2 and I had a romance with Ashley in ME1, and I want to stay with her in ME3 too, but I want to have a romance with Miranda in ME2, so I ask you: Is it possible to be with Miranda, break up with her after the romance and then get back to Asley in ME3? Or Ashley will be mad on me?
