<human>: Summarize the given text in a few sentences.

I've known this girl for about 7 years now.  We've been talking and hanging out a lot lately, and I've finally got feelings for her. She doesn't know this, as she just got out of a relationship and already seems to be into another guy. 

During a conversation, the topic of dating came up the other day where I asked her a "hypothetical" question as to whether she'd go out with me if I asked. She thought for a few seconds and said, "No, because I've known you for so long." or something to that effect. During the same conversation, she ends up saying that I'm a great guy.

The weird part is she ends up getting into guys who aren't exactly reputable. She realizes this is something she says she wants to change and stay away from, but she doesn't really seem to try.
<bot>: A girl I like is into questionable guys. I've known her for a long time and that's her main reason for not being willing to go out with me.
