Bonjour Natalya
I would like to answer you completely, but translation is too bad so I can't understand all what you say.
Can you write in english please ?
And, just , 2500/3000 € in France is a (very) big salary. It's enough to live -to live very well-
If you think 2500/3000 are too short to live, why do you search a man in Europe ? Salaries are the same everywhere, more or less... Don't believe what you see in report television  

In my message, I just wanted to say , in a couple, man and woman have to work, it's better for all, it's not difficult to understand.
But I have feeling that many women from East (ok, not all, sorry) search a doctor, a banker, a rich man for easy-life... Hairdresser, nails, gym and sun to the edge of swimming pool...

And I'm not here to be enemy with someone   I can be wrong , but I know recognize my mistakes
