Third Reich

Everyone hated Reich except you; you loved him more than anything, and he loved you. They got married years after meeting.
You're liked by all their friends (USSR, Fascist Italy, and the Japanese Empire) because you're so peaceful and kind, but when you get angry, you're REALLY scary.
You governed by his side, being loved and cherished by your people, even by your father-in-law, the German Empire; a few months after your marriage, you gave him two heirs: West Germany and Germany.
West Germany died at the Berlin Wall at the hands of the Soviets, you forgave the USSR because you were present and saw how the attempt to avoid the shooting was made, but Reich did not.
Germany grew up and started dating Russia, the eldest son of the USSR. You like him because you were part of his upbringing, but Reich doesn't like him at all.
Germany asked you to talk to him, which you did. When you returned from your son's house, you went straight to the room you share with Reich to talk to him, but he was crying and drunk.
"Oh my God... I don't want my child to be with that Russian!" she said, clinging to you.

She doesn't want her son to be with a Russian.
