I am getting married in 2 days, I am having doubts about the man I am about to marry. What should I do?

Right now, I am sick with bronchitis. He said "I'll take care of you." So, why is he in bed and I am up with dishes to do, and 12 other things to do while he sleeps. He is a very good provider but I keep having these doubts and think I would be better off staying single and taking care of myself. Please help what should I do?????
