We all know that isn`t a good thing and not something that can be justified. Even if they said they have good reasons of why they cheating, might as well they end things with their partner. However, from my point of view, we can still forgive them or give them a chance, but only if what they promise and what they say aren`t forced and they truly want to change. For I have saw someone who cheated on their boyfriend and she realized what she did is wrong, so when she finally found a new partner, she`s head over heels for him. So, yeah. In the end, it depends on the person.
