Hi Lauren - personally I would get rid of the car before you go. If you keep it it is another excuse to come back home! Just think of the money you will be saving. If you decide to come back after a few months you can always get another car.
My daughter was in a long term relationship far too young. She was with him from the age of 14 until 18. She turned 18 and decided she wanted more out of life. They split and within weeks she had bought a ticket to Oz, sorted out her visa and we were waving her off at Heathrow with her backpack. She stayed in Australia for nearly a year and she doesnt regret it one bit and it was the best experiance she has ever had. She managed to scrimp by staying in hostels - yes many a time we had to bail her out and send her money out. She got work in bars, restaurants, exhibition centres laying carpet tiles, delivering wheelie bins off the back of a lorry! We thought she would be home in a month but fair play to her she done it and it is alot further away from home than Egypt! and she done it alone and didnt know anyone in Australia apart from a friend of my hubbies cousin that she met up with and spent Xmas and New yr with in Sydney.
