After playing it again, since it was a while, i honestly can only shake my head about the people who demand loyalty from her, when she literally fucked the MC when he was already in a relationship and after all that he ran off and the "believe in me, i'll be back" shit is even more unbelievable when a criminal like the MC says it. There is not a single reason to even believe that she'd wait because this whole relationship was fucked up from the get go.
It might be ok to think that someone in a normal relationship is loyal to a certain extend, 8 years is a very long time to be loyal with not seeing each other so that thought is very unrealistic, but in relationships like this? Come on.
