Help me understand the ending
At the very end she speaks with her older boyfriend\husband, and asks him to go for a walk down to the river\creek. He says he will meet her down there in half hour. She's happy and goes by herself, spreads out her blanket and sits on some rocks near the water. Her hat blows into water, and she goes after it.
Credits roll.
There is no suggestion that the river\creek is dangerous, so there is no indication that she drowns or something bad happens.
