Just that really.
I met DSC when they were 4&6, I've been with DH now for 6 years.
There's a lot going on with us at the moment. We do share 1 DC too who is 2.
This is something that I'm curious about though, what would be expected / reasonable post any future split.
To be perfectly honest, I don't think I'd have any desire to maintain a relationship beyond times when I'll inevitably see DSC because of our shared DC.
I certainly wouldn't want anything like overnights or taking them out alone/doing any sort of parenting anymore tbh. The idea of my son being my only responsibility is very appealing.
