If he wanted to avoid this exact situation why wasn’t he just upfront with navier the entire time? If she knew that the only reason he was divorcing her and marrying rush to was so that the child could be seen as an heir to the throne she probably would’ve talked it out at least.
Homie, untreated postpartum or not, you have no excuse to neglect your children and demand your husband neglect your children too. If you are jealous of your children because they became the center of attention in the life of you and your spouse, you were never ready for children.
It wasn't postpartum..more likely she's just selfish and greedy. She just wants the love and attention of the ml all to herself.. it doesn't matter if they're their children.. narcissistic people are like that.. it's always gonnna be "ME! ME! ME!" for them..
