How do I get married?

To get married you must get the girl you want to red heart, have seen all of her heart events, upgrade your house twice, buy everything on the saturday shopping network, especially the big bed, then buy the blue feather and propose to her.
Unless you are getting married to the goddess, then at anytime you can propose, one week after she accepts you get married.

Anns heart events are:
Black: at Doug's Inn between 10:40am -1pm
Purple: on the second floor of the Inn between 10am - 1pm on a Wednesday, Thursday, Friday, or Saturday
Blue: at Doug's Inn on Monday or Friday between noon and 7pm ( you must have an empty item slot for her music box)
Yellow: Doug's Inn Inn on Wednesday, Thursday, Saturday, or Sunday between 10am and 7pm

PBerry 2. Throw a flower into the godess pond for 10 days straight and she'll reward you with the berry. ( if you don't know already the goddess pond is above the hot spring)
PBerry 3. When you bet on the horses during the derby race, you can win medals. Exchange 900 medals to Mayor Thomas to get the berry.

PBerry5. In your second year you can have your dog join in the Dog Frisbee event on Summer 01. The prize is a Power Berry, so practice throwing the frisbee with your dog when it becomes an adult in the Fall of your first year. You will also have to buy the Frisbee from Won for 5,000 G.
