How do u handle ur parents breakin up?

ive spoke to them tuns about how im ok wid it or if i feel abit down wid it im always wishing 4 there happyness but it always gets to me when they argue or when there talkin behind eachothers bks they said that they are gonna try and be friends and i understand that they r gonna still fight but shudnt they walk away from fightin while there kids are there so it makes it look like things are ok ?is it normal to want one of ur parents to move out right away because of it ?
