Should I stop being friends with her?

let bob be bob----I had a friend like that---nigh unseparable we were from 4th grade to 9th grade then I started hanging with others--she stole every guy I liked and we grew apart--we still talk from time to time--but we're completely different---I've got 3 kids now and she's still dating......so people grow apart---sad to say and it usually happens in high school or shortly there after---out of all my friends in high school i still talk to maybe 4 of them....let bob be bob---but don't let bob use you!! or walk all over you---don't be available every time bob needs you unless bob does the same in return...
