moving

my whole family lives in a different state, i want to move there with my son who i have with someone in wisconsin.can i take my son against my fiance' will. he has a drinking and drug problem, i want out!!!!!!!!

assuming that you didn't marry...

has custody ever been established?
does he play an active role in the life of the child?

another state - would be how far?
is visitation realistic?
can you/dad afford the costs of transportation?
