Can someone help me decide?

Recently I have decided to go on with my studies - to get a degree (I has studied til diploma level) I am engaged and planning to get married end of next year. My fiance is going to finance me to study until i finish (that is at least 2 years later) which means I won't be able to get married as planned and I don't know whether we will be financially ready when i graduate 2 yrs later!!!( He will be 30 yrs old!! and i'll be 26, and i know our family will have lots of questions to ask about our marriage) I think this degree I have to get but marriage is another thing.... :( Also, we'll be separated while i go overseas for further education cos where we are right now , they don't have enough resources and lecturers... I need advice!!
