This premise is honestly just dull. She was too young to understand, wanted to have fun with her friends instead of staying cooped up 24/7 with a husband whom seemingly didn't give two shits except for his position and next heir, a child she didn't know how to take care of and WAY faster then normal just shut down, taking after his father and just straight up hating the mother. It is truly odd that the only way she could see her friends was to go to social gatherings like that were predominately for single people. Why did she not invite people over?
Honestly, that kind of person might have had a miserable life, but that does not warrant a reincarnation for a "bad" character.
