I don't know how recent her bad experience with men have been, her abuse and whatnot, how recently she got away from all that, but she might just need some time to process it in a healthy way. It might be a completely understandable reaction to trauma that she will work through if given a little time.

However, if all that is basically ancient history then she may have failed to work through it and need some help to do so. Unfortunately, I wouldn't know how to go about that, and it's good she's seeing a therapist, hopefully it's a good one.
