scared asf rnnn/ need advice asp:(

So my parents have been distant with eachother. my dad works out of state and comes home about once or twice a month, when he does come over he usually just works in the garage or sit around. Sometimes he yells at my mom for stupid stuff and my mom gets sad and stuff and they ignore eachother. When i called my dad and finished talking to him and said "ok ill let you talk to mom" he was like "why what does she want?" HELLO? SHES YOUR WIFE WYM. i gave my mom the phone, he said the same thing, they hung up after like not even 20 seconds. Honestly it just really scares me because i dont know whats gonna happen, like if its just gonna keep on, do they not love eachother anymore? and are they just staying because of me. i really dont want that and i dont wanna talk to them about it because im scared if one of those things are true. advice pls?
