She didn't and-or doesn't know what the fuck she did, I don't know what she did and anything about your guys "Relationship". She didn't deserve this, she didn't do ANYTHING wrong, she doesn't know what she fucking did wrong, so just fucking tell her, please.
You fucking bitch.. You have caused Marcus so much fucking pain and confusion, she is most definitely likely sobbing and crying her fucking eyes out, as you do whatever the fuck you are doing, and just be casual about this. She is fucking quitting because of you and your bullshit life, so many god damn people care about her and what she's going through right now, and you fucking made it worse, I hope you have a great fucking life with all the fucking guilt.
