DC often get an absolutely shit deal when marriages break up and often have to accept their separated parents embarking on new relationships and having to be part of a 'blended' family with DCs from the stepmother/father added into the mix.
Some step/parents that complain about finding these DC hard work and their behaviour difficult to deal with. Not exactly rocket science that DC will be disturbed by having to share living space, and time with their parents, with people they are not related to and not having the security of living with, and focused attention of, both parents which is their birthright.
A lot of marriages break up way too easily these days as the parents want to be 'happy' or have 'fallen out of love', 'want a newer model' etc, etc with the DC dragged along for the ride with no choice in the matter.
In terms of abusive relationships, it could be argued that you should know your partner and their background well before bringing children into the equation which seems to be a very controversial view

Is it really impossible for adults to put their 'happiness' and new relationships, which would have an impact on their DC, on hold until their children are grown up?
The damage is often played out when they become adults as children will accept almost anything from their parents as a survival mechanism until they are old enough to question it. It is thought that DC are resilient and will get over it but I think that is a fallacy self absorbed parents tell themselves to make themselves feel better.
My 17 year old DD is the only person on her college course whose parents are still together. I find that shocking and really sad.
AIBU in thinking that this is a ticking time bomb in an explosion of mental health issues in the next generation and the implications of divorce/separation on children's mental health should be much more ingrained in the morality of society?
