<human>: Hello r/relationships. As a full time college student and working part time i barely spend time at home, but for the past few months things between my parents have gotten tense. My dad has been a great father and mentor to me and no doubt i wouldn't be where i am without his help as well as my mom. But last week my parents were arguing and going at it real hard. You see my dad for the last few months has been thinking my mom has been cheating or at the very least flirting, which i strongly think is not true and yesterday as their were arguing my mom ,in the heat of the argument, in front of the whole family, said my father use to beat my mother. I was shoked, although i never saw my father put hands on my mother to learn this broke my heart. I don't know how to go about this situation, its tearing my parents relationship apart. I think my dad is paranoid, i need help on how to go about this. I know its not my responsibility but i want for all the argument at home to stop.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Parents been arguing for a few months, father suspects my mom is messing around somewhere else which i believe is not true, moms tells her kids dad use to beat her, i just want this argueing to stop.
