<human>: Summarize the given text in a few sentences.

Good Morning,
I have read reddit for a while, but this is my first time posting. 

I lived in Seattle with an ex for 11 Months.  The whole time was in the same apartment.  I was not on the lease, I was not on any of the bills.  The property management company had me fill out background check paperwork.  When rent was due, I wrote my checks to the management company.  To settle the costs of utilities, I would either pay extra rent or give money directly to my ex as the bills were in her name (save the internet bill, which I transferred to her when I moved back to California.)

About a year after we split up and I moved back to California, my ex left the apartment and moved to another state.  When she left she had outstanding utility bills.  Approximately 3 months later, I started getting calls from bill collectors trying to get money from us.  They claim that if they do not get money soon, they will impact my credit.

I have had sporadic contact with my ex.  She has not been able to pay off the debt yet, and I cannot confirm if she has setup a payment plan.  I have perfect credit and intend to keep it that way for obvious reasons.
<bot>: My ex accrued debt at our old apartment, long after I left, I was not on the lease.  Debt collectors want money from me.
