I think maybe she just needs a break? Can't blame her.. She's been through a lot, and just wants to have some time not thinking about guys. I wouldn't worry about that. Love will find her when she's ready to be found. In my experience, the best relationships are the ones that you never planned to have.

But I would start to worry the moment she starts turning guys down. I mean when she deliberately chooses to stay single instead of dating a guy that she actually likes. Then I would be worried, and take a serious talk with her. But for now, just let her live the life that she wants to live, and let her feel that she's done with men. I think she needs it.
