Oh and to add another issue here, if you claimed asylum as a refugee from Libya, and then made it appear you went back to Libya for a legal marriage, that will raise all other issues since you are not allowed to return to your home country you claimed asylum from until after you become a citizen.
Plus even if the scam was successful and you sponsored your spouse, if this issue was ever caught at anytime in the future, your partner would have any citizenship/PR status taken away from them since it would have been obtained fraudulently.
