I'm going to ask her out while she's going through something.
Why are going to ask her out now?
Maybe she's more likely to agree to go out with me if I ask her now.
If she's going through a lot of things in her life now is not the right time to be asking her out. Wait until things have gone back to normal for her before asking her out.
Does she have to be a virgin or never dated before me to be considered good enough to date?
I'm not sure what you are asking about just now, but I would say that your own preferences are your own business.  I would still have to advise that you not try to pick up this person while she is distracted by personal issues, however, as it is not fair to her.  Let her deal with her problems, and then she make a decision about who to date when she can give it her full attention.
