<human>: She feels like she is developing a crush on another guy. They flirted when we were dating and flirt even more now that she broke up with me and it looks like she's trying to get in a relationship with this guy. 

She says that she is not sure if she'll like the guy or not, and said that she could possibly see us dating in the future if things don't work out with him. She has also assured me that she likes me much more than this guy, but broke up with me because she felt guilty of liking someone else (she only liked him a little bit)

Should I take her back if things don't work out with her and this other guy? I love her and miss her, but I'm hurt she has feeling for another guy. It also doesn't seem right to have her take a break and just have me as a boyfriend to fallback on since things didn't work out with this other guy.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: What should I do if things don't work out with her and this other guy? Take her back or should I forget about her now?
