Mack,

Apologies for the unfriendly greeting the other day; my sentiment towards you has not changed though. What you two have done is truly reprehensible. Someone your age ought to show better judgement and restraint, and I have a hard time imagining you being a good influence on her life given your role in this disgraceful affair--that is to say: you are a piece of shit and should be ashamed of yourself--do better. Even so, I know that you care about each other and I hope you treat her with kindness and consideration for the time you get to be with her.

In case it's something you care about, and since I would have preferred to know sooner: She has not been faithful to you over these past two weeks.
