This sounds like really abusive, controlling behaviour. I mean, if a woman were posting here that her husband got mad at her for working out near a man at the gym, watching a show that had a man with his top off and daring to talk to male coworkers, we'd all be telling her run for the hills.

This sounds like domestic violence from a woman against a man. If she won't go to counselling, get out.

Hi,
I would recommend you use whatever her passport shows. So, Arshi Meradloo in Last Name (as you yourself guessed) and no middle name. They usually want to see the same stuff that is in your passport. One time I had to pay $80 to change my name in a plane ticket to the US because I had only used my first last name (I have two, as every Spaniard does) and it didn't match my passport name.
I don't have a middle name either and I think that I wrote None, or maybe I drew a dash in that field.
Cheers
