"You should forget about me, because I'm going to die and I love you-"
Stop right there. Just stop. Yes, I'm most likely going to die, and yes, I do love him, but this is the worst way to go about it.
You want to make someone "forget" about you? As if. Honestly, it won't happen. And when you die, it'll just be so much worse.
So how does one go about saving their significant other from heartbreak?
No, no, no no no. That's the last step, you hear?
The first step is to get them to hate you. Yes, you heard correctly. From now on, hatred is your sharpest spear, your densest shield. Make. Them. Hate. You.
Afterwards, they'll eventually lose interest in you. And, yes, "forget" about you.
And then, and - mark my words - only then, do you save your significant other from heartbreak.
