My best friend/ bridesmaid got engaged recently ( 8 months after me ) and just chose a wedding date two weekends after mine.  (I set my wedding date 6 months ago).   I'm just having weird emotions and am wondering if anyone ever had this happen to them? 
Side notes: We have mutual family friends and I'm also concerned about her focus and dedication to being a bridesmaid at mine.  Do I offer her an "out"?
