I had a bit of a similar situation in my pledge class. To me, it sounds like this girl is just really enthusiastic and wants to have fun with her new sisters. Unfortunately, she seems like she takes initiative without regard for the consequences, like when she bought the flowers. I think she meant well. As for her brushing you off, some people are going to be snobby no matter what. If you and your PC made the effort to include her and get to know her and she was still rude to you, that's not your fault. You've done all you can do.

My suggestion to fix the situation with her is to have an honest, polite, non-confrontational talk. You could say something like, "hey, I know we weren't really close during our new member period, but I was just wondering if you'd like to come see a movie with some girls from our PC." She probably realizes that the way she treated you during your new member period wasn't right, and hopefully she'll want to make amends and move on. If not, at least you tried, and like I said, that's the most you can do. If she continues to cause problems, I would recommend talking to the person in your chapter who is in charge of conflict mediation (sisterhood chair, chaplain, risk management?) and try to work something out that way.
