Girlfriend has two Facebook accounts?

okay so I got on to check my FB and it tells me to add my girlfriend on another account. It's a fairly old account, she said she deleted it awhile ago because of drama with people on it. This was before she met me. It was deactivated, because it would never come up in the search menu. But recently it got reactivated. Her aunt claims it was because she accidentally reactivated it, trying to do something on farmville on her main account, but it's been used recently, and it used the some 21 question app. I don't know what to believe right now. It also says she's interested in men and women on that one while her current one doesn't list an orientation. Not sure what to believe here.
