Anyway: it depends on your nationality how easy to find a girl friend. If yo go to the Ally Pally ( Al Ain Palast), the 49ers (Dana Hotel) or to the Night Club in the Meridien Hotel, these kind of girls sitting there like chicken in the cage and are waiting for some guy to pick them.
Of course these girls are no prostitues (he, he) and you do not to have to pay for their service. But - please be aware that they will ask you for money to go on a visa run or to help out to support their sick mother etc, etc. You are also suppose to spend your money on other things like Willie stated above.
How easy it is for you to get a girl like this depends on your passport. If you are a Westerner - no problem at all. You can be old and ugly as long as you carry the right kind of passport. Most of these girls here are on a visit visa and looking for somebody to take them to a Western country.
I do not care about your lifestyle, but no respectful women would get involved in a 3 months relationship. In this case you get what you pay for.
Stay healthy.
