My parents also told me about that too...so it makes me quite concern where this relationship between Natsu and Arata
And once a partner cheats on you, they wont think twice about doing it again, just proves that they shouldn't have stayed together, an abusive person and a partner that clearly didnt love him enough to not cheat
Maybe it's just me but my Mom always tell us that if our partner ever raised their hand against us once it has a high possibility to happen again.
And let us appreciate that the only likable character here, Ryouma AKA homewrecker. He stopped having sex immediately after Natsuki told him he was in a relationship and even had the courage and character to talk to Arata to possibly amend the relationship of the two.
