focusing on the actions of others is not going to take light off of you.
you cheated, and no you are not the only person to ever cheat. but to KNOWINGLY lie and not tell the man you spent 4 years of life with is completely wrong. it is very hateful to be honest.
you and gem schemed together to not tell him and to further play scorpio for a fool, pretending like you got together months later.
you are saying that scorpio has no intelligence, he is a fool and who cares if he does not know. just as long as you two can go unscathed and live happily.
you further screwed over scorpio, who is now deep in worry because he thinks everything is his fault now. you left him believing nothing but lies. that is not something to easily get over. in reality, you are selfish and heartless.
