I really doubt the kids are keeping her there, she is detached from them and probably would be extremely happy if she only had to deal with them on school holidays and leave them in Dubai with Cem during the school term.
I would say the real reason for her staying in Dubai is to keep herself afloat financially, she has a few sponsorships there, which she would not have anywhere else, certainly not in LA or in London, she got the RHOD gig only because she was living in Dubai, she certainly wouldn't get on any of the other RH programmes. The house help, the cars, property etc would be unaffordable elsewhere. What else could she do, she has no career to fall back on.
"when did she become so obsessed with her sex life and hanging on chandeliers and all the other stuff she says now. Why all of a sudden is she obsessed with sharing such a initmate part of a relationship?"
What is that saying 'the lady doth protest too much' ...... I am really beginning to believe he is gay and either she knew it from the outset and was okay to have what she thought was a young cute guy at her side to try to bring interest and enhance her profile, , or he still has not fully come out of the closet, maybe in denial to himself. But when you see him with the other gay men that Caroline hangs out with, it is very clear that he fits right in.
I had a friend who had a boyfriend who turned out to be gay, needed a girlfriend for his career and the circles he was hanging out in, she said he knew exactly what to do with a woman's body during sex, took her a while to realise something was not right about it all. It took her ages to recover from the betrayal of finding out he was gay.
