I cant believe this is happening...

As some of you may know, im getting married on 25th october in vegas and one of my best friends decided to go ahead and book to have hers just 4 days before me (which in all honesty did piss me off slightly) However my friends reception venue fell through as they sold it so her and her h2b were going to look at other venues on saturday. H2b said he didnt feel well so didnt want to go but my friend persisited and he then admitted he couldnt marry her and that he doesnt love her anymore. She is absolutly devastated which is obvious i know . She will get through this as she has a good set of friends and family around her, but i cant help feeling guilty that im still getting married and she isnt. I know im doing this to myself and that i cant help it but i cant help it!
