Is it normal...

To feel scared about getting married as time gets closer? I feel like lately Rob and I have been arguing a lot. I know we're both under a lot of pressure, but its like he's gotten so sensitive to everything and so have I. Then it's like stuff we've planned TOGETHER he suddenly wants to cancel and it's like HEY I'M IN THIS RELATIONSHIP TOO, YOU CAN'T JUST CANCEL WHEN YOU FEEL LIKE IT. I don't know maybe the arguing and worrying has got me all wound up. Is it normal to feel like this??
