Harvest Moon: Island of Happiness Q&A

Ok. I have like, a best on this site, but i can't figure out how 2 get her on my friends list! pleez pleez pleez help

Ok so i'm having a hard time deciding who to marry. I have narrowed it down to either Denny or Vaughn but I CAN'T DECIDE! PLZ HELP ME! TT-TT

1. Does the game end like previous Harvest Moon's? 2. Can your child grow up?/Do you become your child later in the game? 3. Do you go on dates or to festivals with your possible bachelors/bacheloret tes?
