yes it got approved, i could extend my visit till april 2014. Our reason in the application was, that we want to explore more our relationship and that we need to stay for 1 year without interruption together, so that we can apply for common law union and after that starting the Permanent Resident application. I am extending my visa now for the second time, this time i put as reason, that i want to stay with my partner to await the processing time of my PR application.
Make sure that you show in the application that you have enough funds to support yourself, or (and) include a supporting letter from your boyfriend in the application with paysubs, bank statement etc. ..... I included also proof that i have health insurance during my stay, which is very helpful i think.
good luck
