When I knew the names and general situation with her entire family that lived in the same city as her and she kept forgetting my 2 sisters names. At some point, I was like..she's not forgetful, she doesn't give a f**k! LOL...I never stood her up and she stood me up numerous times. AS I ditched the relationship and had some time to think (I was very hot on her) I realized she was never really into me. Lesson learned in my 20's..and i'm old now.
