My high school best friend and I had a falling out in college, but she was my main go-to for the first 3 years of my relationship with my FH. Our old roommates were also there for a large portion of it. When my ex-bff and I had our falling out, I backed off because I had other friends to go to and she didn't.
I miss them dearly and we keep up on facebook and whatnot, but we're not close like we used to be, since I live 3 hours away from all of them now. I definitely want to invite them to the wedding, but we're not sending save the dates and I want something more personal. What do I write to let them know I want them there without making it weird?
