LoL so what you are telling us is for the moment you have the power. LOL
To me your older sister is encouraging him to keep trying, accepting all the flowers and things and taking him up on all the dinner invites. She is keeping his hopes alive for getting back together. Not quite the thing to do if she just wants to be friends now.
Your next sister in Dubai, is she military, or civilian. Big difference
in how I would answer this. If she is in the military she should go to
a chaplin and talk things over with what is bothering her, or a friend
I don't know if the military would send her home or not. but they should have some sort of a help system setup that she could go to.
If civilian and she can leave, she should come home if it is upsetting her that much. Alot of people have a tough time being in a foreign country working, especially a country that women are not considered equal but of a lower class citizen. That would be very
hard for a woman who had never experienced it before and is probably away from home for the first time. (she is very homesick)
would be my guess. There is no shame in admitting the job, location, people who she works for are to much to take. Working in a hostile enviroment to westerners would be a difficult situation.
and being a nun living in a shed isn't such a bad thing either
