Lady Isabella's Scandalous Marriage

I loved and adored you, but I drained you like a thirsty man at a spring. I loved what you could give me - your admiration, your acceptance, your love, your forgiveness.  I forgot to love you for yourself.

Marry in haste, Repent at leisure.

"You are in no position to make threats to me."
"I don't have to be. Even if you shoot me, you can be sure you'll never get away from Hart. He's a fucking obsessed bastard, and he's touchy about people harming his sisters-in-law. You will be praying to have me alive once Hart is on your trail."

Dearest Mac,
I love you. I will always love you.
But I can live with you no longer. I've tried to be strong for you, for three years I have tried. I have failed. You tried to remake me in your image, dear Mac, and I tried to be what you wanted, but I no longer can. I am sorry.
I want to write that my heart is breaking, but it is not. It broke some time ago, and I have just now realised that I can leave me heartbreak behind and go on.
The decision to live without you was a painful one and not lightly made. I realise you can legally cause me much harm for taking this step, and I ask you, for the love we once shared, not to. It could be that I will not need to leave forever, but I know that I need time apart, alone, to heal.
You have explained that you sometimes leave me for my own good, so I will have a chance to recover from life with you. Now I am doing the same, leaving so that both of us have a chance to breath, a chance to cool. Living with you is like being with a shooting star, one that burns so brightly that it scorches me. And I am watching the star burn out. In the end, Mac, I fear there will be nothing left of you.
I know you will be angry when you read this, because you can grow so angry! But when you stop being angry, you will realize that my decision is sound. Together, we are destroying each other. Apart, I can remember my love for you. But you are burning me. You have exhausted me, and I have nothing left to give.
Ian has agreed to bring this letter to you, and he will inform me of what steps you decide to take. I trust Ian to help us through. Please do not try to seek me yourself.
I love you, Mac. I will always love you.
Please be well.

Isabella
