Need a favor.. (Chicago)

Indescribable situation.
.
Fiancé of 6 years and I split up tonight and need immediate rental.
.
Work 70+ hours a week and will only be there to sleep! No hanging around like a scum bag and won't have visitors.
Just broken hearted and don't know where to find a quick, affordable, unintended spot to get some space.
HELP A POOR LAD! Have $$ up front to make it worth whoevers while.
