This is what I'd text her.
"Babe, listen, I love you. I want to marry you. I'll lick your arsehole out every night if that's what you want. You want to bang me with a dildo, let's do it. I don't care, just give me a chance. I promise you'll love me like I love you."
If that fails, just f**king get some GHB, set up a Fritzl style sex dungeon. Tie that bitch up, f**k her, have kids with her and f**k them. Give them a bit of a sink and a fridge and you're set for life.
