It is not your fault if your parents do not live together anymore and they continue arguing: it does not depend on kids and it does not influence on they love they feel for you.
Whatever it may happen to them, it will not on effect on the relationship your parent share with you, indeed, it is forever! Even if they decided not to be a couple anymore, they will always be your parents: your mum and dad!
Of course, kids are not happy when their parents decide to split but this does not mean you will not have a family anymore! Your parents will always be there for you and their arms will always be there to host your fears and worries. You may feel alone and not understanding what is going on. There is something you can do: share with them your emotions.
