I don't understand at all how someone can be your fiance when you even consider taking a break because of six weeks. You want to marry this person? Anyone I want to marry I would never want to "split up" with them at all. The point of marriage is to be together forever or whatever. It doesn't sound to me like you take this relationship at all seriously. You should just end it and go f#$k whoever it is you are after and let this girl find someone that is truly in love with her.
