<human>: I (24M) recently started dating a girl (22F) back in mid-April. We have gone out several times, kissed/made out and nothing else but haven't had the "determining the relationship" talk. 

However, last night I found out that her ex-boyfriend found out that she was dating someone else (me) and he was apparently crushed and really hurt by this. After I found out, she then told me that she didn't want to date him anymore but couldn't stop feeling terrible because she knows it crushed him and she didn't want to hurt him.

Is this a bad sign on my part? Does this mean she isn't over him? What is her logic behind this? I just don't know what to think because I feel like my "relationship" with her has potential but now I don't know...

Can you condense the text into a few key points?
<bot>: Found out the girl I have been dating for a few weeks, recently had her ex-bf find out that she has started dating someone else and she is upset at the fact that she hurt him...
