Is this girl into me?

I'm a girl, and from reading this i thought she could be into you.. but when you said she has a boyfriend already? I think maybe if she didn't have a boyfriend then you should definitely go for it anyway, but if she was getting bored with him, she would have ended it with him already. Act normal around her and play it cool. If you feel the urge, be more flirty, to subtly let her know you're into her without freaking her out too much if the feeling isn't mutual.
