Ok, let's talk clear: if you can't leave Israel because of your job, you earn good money in a responsible job (no supermarket cashier, that is?). So, be a gentleman, send an electronic flight ticket per e-mail to "your" lady. If she doesn't come, you lost a few hundred bucks, but she can not use that money anyhow. And if you make hotel reservations (e.g. on booking.com) you can cancel them and possibly loose one day's fee. So, what is the problem?
