It would be under her "Intro" but even if she is married she doesn't have to say that she is. I am single. It does not show up on my "Intro" that I am. I looked on my page under the "About" section. I clicked on my Relationships and Family. There is says that I am single.

If she tells you that she isn't interested then move on. She might change her mind and contact you later but don't try to persuade her to go out with you.
