Dude, at least give her divorce papers or something now that the cat is out of the bag! Did you guys know that, even now, japanese women can't go back using their former surnames right after they get divorce and they have to wait a certain time before being able to change it back again? And now what If she wants to get married again what is she going to do? Present times are a bit on the relax side if you just decide to live together with your partner (tho I think there's a law that if you have lived together for a number of years you're considered as a married couple) and nobody will criticize you but during that time, and a Japanese woman on top of that....... Ugh, so frustrating!😡
