[quote pootleforPM]@sassbott I think that's the heart of the matter. RPs like yourself tend to have their lives set up in a way that facilitates being able to finance, care for and parent your children solo in the time they are with you, any partner that then comes along is kind of like a bonus - not really needed on any level by the children, but available to support in event of an emergency, and hopefully just have a nice relationship with the children. Even if their NRP DF were to die, then they are already living in their main home with the RP and life would, to a certain extent, carry on as normal.
Many NRPs have their lives set up in a way that does not factor in caring for their children full time. So SDCs suddenly moving in, particularly if the NRP were single, would present a massive headache practically - might have to change jobs, take a salary hit, move to a different area to get more family support, source and pay for childcare, deal with potentially angry or bereaved children who up until now have spent most of their time with the RP. And I think a lot of NRPs (and mainly we are talking about men here let's be honest) would really struggle to cope - hence needing / expecting more support from their DW/DP if they have one in caring for the DCs than would ever be expected the other way round. It is rare that DCs live mostly with the DF, and would then have to go and live with their DM if he died, if that were the case I expect the DM/NRP would similarly struggle to cope.[/quote]
I definitely agree there would be more expectations on the NRPs partner/spouse in these circumstances than the other way around. As you say, the RP would already be caring for their DC the majority of the time, the upheaval may not be to the same magnitude.
Which is exactly why I would hate it. I do not want to essentially become a mother (I don't mean in the sense of replacing their Mum but in terms of practicalities) to two more children overnight. That would make me miserable I'm fairly sure.
