My ex girlfriend cheated on me and moved out. After separation in November last year, she demanded I pay her back full amount of bond ($1400) which I did and she also took various house hold Items like the fridge,couch,TV and washing machine. We had an electricity Bill come in shortly before she left which she did not want to be responsible for, that bill totalled $1000 I payed $300 of it so now it is $700, she didn't want to be reasonable and come to an agreement she just wanted me to pay the lot. I stopped paying after I payed $300 because I felt after giving her the full amount of bond and having to buy myself new house hold items to replace the ones she took not to mention being stuck with a house to pay for and now the bill is so overdue the company is threatening her credit file if the remaining isn't payed in 14 days. (Bill is in her name.) Is this my responsibility am I at all liable for any of this?
