Miles, no offence intended but I had no idea until i saw your picture that you are so young....you look about 20-21?
OMG.....I have a hundred more idioms for you, none of them would encourage you to get married at this point.
You have a better than 1 in 2 chance of getting divorced within the next 3 years ( US figures on the divorce rate). The younger the people getting married the higher the rate of divorce.
If you don;t already live together then before you tie the knot you should for at least 6 months.
Sorry if I am pouring cold water on the marriage thing but too many people think that marriage is cool ...until they are in it....and most of the time ( statisticly ) it is just plain hard work and often that stupid piece pf paper changes relationships forever.
I hope it works out for you and that you will find a way to be happy together but if you want my advice ( probably not) DON'T DO IT..but if you must ,at least go to Vegas and be married by Elvis.
