Thank you very much for the answer,
maybe it helps for friends who are in my situation,
We learned by consulting the lawyer.
Normally I would come to Germany if I came to my wife, min told me that 3 must be married for years, I have to work as insured at least 1 years in the same workplace and that I could leave without any trouble in my session.
but because I came here from a family union over the children, I could sue and divorce whenever I want, regardless of the session. I say 100 as a family union through the children, and it is definitely not a problem and it is said that you will be divorced today after 3 months.
