How do I tell my boss I am quitting?

I am moving away with my hubby to another city. I have been at my job for a year now and I am the only girl in the office. They depend on me a lot. I decided to give them 1 months notice and that means I have to tell them in a month. How do I tell them that I have decided to move?

'Our family has decided it is in the best interests of the family to make a move to another city by July - I've enjoyed my time here, I'm giving a months notice' - I wish you the best and success in your new location !!

well you gotta do what you gotta do sooo... just talk to the boss and dont be rude about it of course... and what can they say or do.. nothing.
