Gotta invest a little more if you don't want her ghosting. In her mind, she's saying either 1) I'd like to be more than just a cheap pump & dump or 2) I can phuck another guy who's a little more interesting (not saying you're not, but you haven't shown any uniqueness or personality through the text.)
Be a little less mechanical and the ghost percentage will drop. Not saying you have to radically change anything, but try putting a touch more effort in. Plus, this is 5 days before the hookup. Plenty of time for her to change her mind, so you need to keep the fire burning.
So a little more effort and/or better timing should help.
Your correspondence is like a plain burger with no cheese, lettuce, onions, etc. Need some condiments at least. Sh1t needs some flavor. The opener isn't bad but you can't talk about "adventures" without engaging her imagination some.
