last month was a bad time day for our relationship us

I have been my planning to marry with a foreigner in indonesia after of this years next year and there are is should be a good preparations for us to make before marriage but doubts are arising on in my mind, it seems it is all impossible for us.  In his plan he will just stay 2 to 3 months to take care of administration and perform the do marriage, and then afterwards then we'd be flight fly to his country.
how about the requirement documents and procedures of each the country?
how can do requirements be fulfilled without a not too long in such a short time *( 1 to 2 months )
what should i do will so we can do marriage marry and I can migrate?

Time sounds far too short - he may have to go back alone, and wait for immigration to give you a visa to his country.  Expect 6 months at least, I think.
