Many would say both but for this exercise, you have to choose.

Ok so I have two younger cousins who were ages 3 and 4 when their dad (my ex uncle) left and cheated on their mom (my aunt). Parents have done joint custody ever since, they are ages 7 and 8 now and probably shifting from one house to another every 2 weeks is something they more or less seem to be born with as they probably only have very vague memories of their parents once living in the same house.
They have one older sister who is 13 now (was 8 when her parents slip up so she obviously has much more memories of her family once being whole and tbh she has a really good memory in general).

So the 13yo eventually ended up putting two and two together and realizing that she knows why her parents separated suddenly (because her dad had an affair). Over the last year or so she has had a lot of Issues with her dad and anger towards him with regards to everything that’s happened in the last 5 years of her life. She dose not want anything to do with her dad, she wishes she can permanently stay at her moms place but her mom dose not think she is responsible enough to stay by herself overnight regularly when her mom is on night shifts so she will have to stick with the joint custody for the meantime until her mom feels she is responsible enough.

So my question was, what are your opinions on how the 7&8 year old’s relationship with their dad will be as a teenager once they too realize that the reason why their mom and dad split when the were so young is because their dad left and had an affair? I imagine they won’t have nearly as much anger as their 13yo sister since they were a lot younger when their parents split but nonetheless, just was hoping to seek seek of your opinions.
