So Cassandra is coming over for the weekend, and i love having her but she doesnt understand.  She comes over alot, and it's because no one else can handle her.  She doesnt listen to others, she doesnt respect ppl.  and i kno she gets upset bc she knos that shes being dumped on me, and she likes it to some extent bc she is always calling me and begging me to take her back (total kick in the teeth).  i dont kno what to do.  if shes not scared that her mother is coming in the night to steal her shes worried that no one loves her bc she is always being dropped on my step.  and if i don't see her at least three to four times a week she calls me bawling to say she is running away bc no one loves her anymore.  i do love her, but im 21, and i need to have my own life too.  i dont want to hurt her, shes already been hurt too much.  what do i do?
