Should I stay or should I come back....?

Should I stay in France or come back home?

FRANCE: I have a job I like, strictly my profession - I'm teaching, only 20 H per week, I have small groups (like 7 pupils), so not much homework to check, etc. However, I'm payed by Poland, so what I earn doesn't even make the minimum salary permitted in France. That's why I can't rent a flat, because you have to provide documents that prove that you have a stable FRENCH job and you earn 3 times the rent. I can't. So I need sb who will do all that for me, and I don't know anybody. The only person that earns enough money is my ex-boyfriend, but one can't really ask him for help... Actually we lived together once, that's how I got a place to live, but it didn't work out between us. I found a free room in school's flats, but soon after I had to leave, because it's actually for French teachers, as administratively I work for Poland. Then I could come back, but I'm never sure to stay. About the money - all that's bothering me is the requirement about 3x the rent, because for me, honestly, I earn enough to get on well!!!

Additionally, I have no assurance in France. And I don't have many friends in my age, so I'm a bit lonely...

So... staying and struggling for a flat and other stuff all the time and keeping my favorite job? Quit this job and try to find another one here? and hope to find a new bf, another reason to stay here (and really, I had only French bfs in my life!)

POLAND: There is a lot of unemployment, I don't want to work at school because it's really difficult these days in there. I have my family, but I can't come back to live with them, as I actually left because of my father... He's unsupportable, despotic,stills treats me like a child=sb who has nth to say, so he wants even to control all my money...

I'd like to go to the city where I went to university, I have friends there, and I can rent a flat without any questions. However, the job is not waiting there, it is not easy to get, and I will never have the same level of life that I had before. With the small thing I earn in France, I can go for a vacation to Poland;) But being in Poland, I'm not sure to earn enough to go on holidays to France or anywhere. But I''ll have an assurance, a flat - but... a job? A boyfriend? A comfort living? Maybe not.

What would you do in my place?
