Can I collect debt from ex-partner for item purchased together?

My ex and I purchased together a $3,200 king bed in 2005. We separated in 2007, she paid me $250 towards my half and kept the bed. I could really use the remaining $1,350 she technically still owes me. There was no written agreement about the $250, and I took that only because she wouldn't agree to pay any more than that. I cannot locate a copy of the original purchase statement from Sleepy's, but do have a bank statement and copy of my check for my half ($1,600) paid to Sleepy's in 2005. Can I still pursue this at this point, and with rights to the full $1,350 at least?
Thank you.
