Should i take her back?

Ok so my ex girlfriend broke up with me like 6 months ago and she has been seeing a few guys since we broke up but now she texts me out of the blue and says I wanna get back together and starts saying stuff like she's been dating 20s and I'm her 80? I don't know what that means but anyways should I give her a 2nd chance it was her fualt we broke in the first place but I think I do have feelings for her still I jusr don't wanna get hurt again
