you can't leaves them rhe love you and you also love them
you can't turn your back on them
even my family flightseach day but we all are still together
just talk to them in a nice way try to make them understand
and won't take any decision that later you'll regret
Talk to them and try to mend things between them. You can start with telling them how their fights affect you
You can try to talk to them individually and tell them how it is affecting you. They should try to work on their relationship. I am sure both of them love you, they would never want their child to be affected by their fights.
