3 or so years ago, my boyfriend at the time borrowed $3000 from me to pay off a dodge migrant agent. He said he would pay me back the debt one day. About 12 months ago, he borrowed another $1000 from me to move houses, as he was unemployed and lost him money on the pokies. The relationship ended in June this year, and he decide to go to his home country to meet his new bride. He hasn't attempted to pay me the $4000 he owes me. I asked him about this a month ago and he claims to not remember me ever lending him the money. I've tried to contact him, and he is ignoring me. I've offered him a weekly payment plan, but nothing. How am I supposed to get my money back?
