It’s not unusual for parents to be blamed by their children for how their lives turn out. It’s also not uncommon for children to have strong influences in their lives whose influences have a greater bearing than their parents.
Consequently, this may play out on an unconscious level in the child’s behaviour and attitude towards their parents. Although children will never consciously apportion blame at their parents’ door as a consequence of their relationship with others, for some parents it becomes clear that they are being blamed.
It’s far easier for a child to blame their parents, than it is for a child to deal with their feelings, particularly if it means them having to address their issues with those influences who aren’t their parents and whose influences have been far greater than that of their parents.
Away from that and even with all the strong influences we have in our lives, it’s up to us to deal with our lives in an appropriate way, without unconsciously apportioning blame at our parents’ door, if they’re not to blame. Sadly, apportioning blame will always have an impact, it’s immaterial at whose door.
