For the sake of her boys, I hope you're right.
Though I think the underlying, small behaviors that make me deeply dislike mursel are hard to fake.
Not getting any of his own luggage from the car, but expecting the boys to be his valet and not even bothering to get up and bus his own plate. Not even wash it, but to just bring it from the couch to the kitchen.
Maybe I forgive these things if someone is a guest. But mursel is not, he is supposed to be living there. Those behaviors are small and ingrained, IMO. Some people are just ingrained with an attitude that they should be constantly catered to and their presence is so amazing that you should feel glad to have them around and honored to wait on them hand and foot.
And it's also that self centeredness that is on display when it's urgent! That Anna stop everything! Right now! To see what mursel built! Yes, it was a cool honeycomb....but it's like what he wants must always come first, his needs must always come first, he cannot wait a minute for her to be done with what she is doing.
