It's been 8 weeks now since my fiance (10yrs) left me for a younger girl 10 weeks before our wedding. Had to cancel everything myself and pick up the peices. Still feels so raw and I feel so lost. Hate that the date is coming up too soon :'(... How did you girls every cope after a big break up? What would your words of advice be? Thank you. Xxxx
