Either you were wrongly advice or didn't seek advice. Making a claim and withdrawing it, when there's it's likely to be refused or the outcome is negative at first hearing. With your Master degree in Canada, there are many immigration streams you could have used to stay legally. The only suggestion in my opinion, is that, if your marriage is genuine you can update your refugee file with IRB and make same copy to IRCC. Your legal representative or consultant will guide you on this. If you're lucky, the member (IRB decision-maker) may put your claim under consideration on public policy for sake of a family member or interest of a child. However, if your partner isn't a Citizen or PR, just forget it. A marriage to a foreign national on temporary resident status don't really hold weight in your case.
