cheating is also never a mistake. you don’t “accidentally” get someone’s number, and then “accidentally” text them or even “accidentally” go out w them. Cheating is a series of choices that you actively make, so it’s not “just a mistake”.
curang tu bukan dugaan, curang itu pilihan. you choose to cheat, you choose someone else over your partner that you once promised you're going to love her & be with her every steps of the way, so no. don't twist the concept of cheating to make you look innocent
