yes. absolutely. did you know they married at least three times? their first personal union happened during the 14th century, and it made them the biggest country in europe at the time.

next one was in the middle of the kalmar union, i need to read more about it but apparently they decided to join eachother as a way to oppose denmark, obviously it caused big trouble and sweden and denmark almost went to war because of that.

and the most well know was their union of 1814, they were together for almost one century, and fortunately the dissolution happened in peace, from what i've read the citizens of sweden were very supportive of norway's wish for independence, so i like to think that while that counts as a "divorce", it was also the start of a more healthy relationship between eachother after centuries of struggle.
