<human>: Can you summarize the given text in a few sentences?

So I am tied between two girls. Girl A, I dated before. She broke up with me because she was afraid I would turn out like her last boyfriend. It was very abrupt and hurt a lot but I got by. Its been almost 9 months now and she has started talking to me again and flirting with me. The problem is I am also flirting hardcore with this other girl, B. I haven't known her for too long but we have lots of stuff in common. I still have some unsolved feelings for Girl A but I'm afraid it won't work out. So my question is, who should I go with, in your opinion. I need evidence so I can make sense of this myself.
<bot>: I like my ex still and she is flirting with me but I have been flirting with this new girl, who should I date?
