I wouldnt want Rose to become a strigoi, even though if Dimitri is. And he would have never wanted her to turn Strigoi for him. There is only so much you can do for love and I think that would be over doing it. There must be another way for them to be together if that is what they really want.
So Im really looking forward to the next books to se what Richelle planned for them!!! I do believe they will end up together in the end and that they will find a way thats good for both of them even if they will have to fight for it!
