I'm having second thoughts

I'm due to get married in May. It's so close, but so far away! But now I'm having second thoughts.. 
I love my fiancé and there is nothing "wrong" with our relationship I just feel like we have different opinions and values. But there have also been times when he asks me why I love him and I can never think of any valid reasons. 
I feel like if he really loved me he would want to help out around the house, cook for me (even once in a blue moon) and not expect me to come home from at 13 hour work day when he had the day off to make dinner, do his laundry, and still have time to 'hang out' before I go to sleep.
It would be easy to leave if i leaves near my hometown but I'm halfway across the country and feel stuck. 
Any advice or insight would be nice especially if you've been through something like this.. Is it normal, will my feelings go away?
