great expectations question

Citation: "You'll drive me to the churchyard betwixt you, one of these days, and oh, a pr-r-recious pair you'd be without me!" (Mrs. Joe Gargery pg. 9)

My book has different page numbers, but it's on the second or third page of Chapter 2.

 

 Question-

 I have a few questions aobout thuis passage.

One is what in the world does the word betwixt mean?  its mentioned more than once before this and i just want to know what it mean!

  

new and revised paragraph

Well, the only thing i have currently not changed anything in my paragraph exsepct the word bunbury so that its not repeating. other than that my paragraph hasnt changed. i wasnt too sure on what word i should use instead of bunbury so i changed it to words like him, it, and he. i think it sounds much less repetitve now.
