First off , you cheated on your girlfriend . That ' s shitty enough . But to make matters worse , now you ' re thinking about not telling her , because you don ' t want to be dumped . You ' re even talking about further violating her trust by lying to her and using Netflix info to prove you were at home when you were actually off fucking some other woman . All you seem to be thinking about is what you want and how you can get out of any possible consequences for betraying your girlfriend ' s trust in you . I am stunned by how selfish you ' re being . You made the decision to cheat . She ' s already in an awful situation with no good options because of your actions . And now to top it off , you ' re talking about taking away the only agency she has in this situation , solely for your own benefit . You ' ve wronged her terribly the least you can do for her is tell her the truth so she can make the decision that ' s right for her .
