Paris is nice for a vacation - but European cities are NOT like cities in the States.
They can become extremely cramped, people live mostly in apartments with the the very rare exception living in a Villa.
I have lived and worked in Europe for 6 years now (Germany, Spain, and now Italy) and the feeling of living in Europe is Completely different to the feeling of living in the "Colonial" countries like the States, South Africa (although changed a lot now with the crime) , Australia, Canada, New Zealand etc.
In these English speaking countries there is always a sense of possibility, finding new ways to do things, changing, not accepting .... but in Europe, it's totally different. It's a very established continent, there's certainly no such thing as the "American dream",
those who have money do, those who don't don't, those who have all the property do those who don't don't, those who have that business contract do, those who don't don't - - and that's the way it stays.
The point that I'm trying to make is that there are many pretty European cities but take a long hard think before you decide to make a fairy tale out of them. The biggest factor in anyone's life wherever they live - is Quality of Life. Is your quality of life going to be better in Paris than in the States.
Losing close friends, losing the system (you may not realise but you know a system of doing Civil related things - registering you dog, where to pay a traffic fine, where to register for voting etc. etc. --- you lose thi system in a European city), living in smaller spaces, less green open spaces, smaller streets, losing friendly familiar faces etc. etc.
Think long and hard about this - Europe is Fantastic for a holiday, but to live it is a total 180.
All the best.
