Can't wait to move out of this stupid flat. The council are just ridiculous, expecting me to fork out £100 a week rent knowing full well I don't have a job nor do I claim a single thing when my ex ran off and left me in a property where he is the main tenant but they don't expect him to pay any of his share. I have to pay £400 rent when I'm not going to be living here either until the tenancy is up so why doesn't he have to pay anything, we signed a contract saying we are equally responsible. Yeah my ass😡😡😡
