I think you are right when the DC are involved with education or say saving for a house deposit/wedding/driving lessons/car letting them live home rent free is ok because all of those things lead to independence, otherwise over the age of 18 they should contribute.
I would disagree that Mum always gets the house; anyone I’ve known has sold the family home and had proceeds split equally between them and ex, though the exes do have custody 50:50 and they contributed 50:50 financially towards the houses in first place.
I think it’s a generalisation that the divorced/separated Dad’s always end up with a higher earning woman or one with her own home. Sometimes yes.
Personally, after 6-12 months of a relationship where step parenting was involved I felt completely turned off by the scenario. I didn’t want my future DC to not be prioritised (financially/emotionally) at any point or to have their fathers divided attention. His ex was difficult and she and I would have been diametrically opposed in terms of parenting style, it wouldn’t have worked.
So me, my earning potential and assets went elsewhere. I would imagine a lot of women would do similar.
It can be the case where the woman has to be the primary bread winner thanks to most of partners income going out to children from previous relationship/s. But it’s not normally a happy circumstance and builds resentment.
As before, you tend to find more SMs than SDs as usually the Mum of children is too busy with them post separation particularly if contact is limited to EOW or similar with the Dad.
