Personally im hoping that the small role in ME2 is a test for all the people that actually love Ashley, and that we will all be rewarded for staying faithfull in ME3. There are enough hints to indicate the relationship definately isn't over, Ashley clearly still has feelings for you, the encounter on Horizon and the email from her clearly show that, holding her photo before going into the Omega 4 relay is the icing on the cake and hopefully indicates the relationship is far from over.
I know there are alot of Ashley haters, but i personally think she is one of those kind of characters you either love or hate, if you actually bother to take a deep interest in her you find that she is indeed a deep and well thought out character, and personally one of my definate favourites in mass effect, lets all hope for a large squad role and romance for Ashley in Mass Effect 3!!!
But with Ash, when she goes beserk on Horizon and doesn't trust you enough to know you arent fully with Cerberus (at least the Paragon route) ... that ended it for me.
Plus it was really hard to resist Miranda a second time ....
