My soon-to-be MIL and I don't have any open hostility, but we're not best friends, and probably never will be. Two people who are both control freaks usually won't get along perfectly in that kind of relationship, so it's probably for the best that there will be a few hours separating us after the wedding. She's a very nice woman, and has great intentions, but being realistic about it, I don't think she's my biggest fan
(My Southern-ness and her Yankee-ness are really clashing with this wedding planning. I will be so glad once it's done with!)
