Her London flat was £2000 a month. And at the beggining of the relationship she was getting £3k a month. But now she gets 5. Its a real info from someone who knows her personaly.
I really don't believe it.
And whoever told you - the info would have come from Anna. We know she's a notorious liar so I can see her inflating her allowance to make herself seem like more than she is.
I think the bf paid the rent on the London flat, so the 2k was probably just for her own injections and for funding her teas as she sat in hotel lobbies.
Now they live together he probably gives her less. She always claimed that once she could afford to, she would buy her boyfriend things and start contributing (lol!). I believe now they probably are on par with their earnings. If anyone can figure out his title we can easily know his salary, which supporting a flat, a golddigging girlfriend and etc. can't go that far.
When she moved to Geneva, she was just starting her scam course so she was able to use the students' money to buy some trinkets for the supposed new place. Which we have still not seen more than a closet. I was too busy with life then but I do recall her buying crystal glasses for their new flat.
