What should I do? Girls please help!!!?

I have been going out with this girl I really like for about 2 weeks. We have been on about 5 dates and I already met her parents. I really like her and she says she likes me too. We hold hands all the time and she leans on my shoulder whenever she gets the chance, which I love. I just added her as a friend on facebook last night and when I looked at her pics, there were some of her and her ex. We bot broke up with our ex's over a month ago. I deleted all my pics of my ex and I but she still has pics of her and her ex. There are even some of them kissing, which kinda bothered me. I told her that I saw them and she said she was going to delete them, but she hasn't yet. Not only that, she commented on this other guy, who's status said "finally done with school". She commented saying "I bet you cant wait to hag out with me everyday" and he said "Exactly, I cant wait to see you my love". This got me kinda worried. Should I ask her about it? I just don't want to be hurt again.
