What was the 'meaning' of the final scene?

In this movie, Leticia is destroyed: her husband whom she apparently no longer loves but is the father of her son, is executed; she loses her job; her car dies; her son is killed by a hit 'n' run driver; she is so low that she steals an umbrella because it is raining; she tries to return favor and affection by buying Hank and hat but is immediately passed off by Hank's jerk dad as someone whose one main purpose in life is provide *beep* juice; and she is evicted from her little house after going through the fear and trauma of knowing that the eviction is coming; and she now is sitting on the street with no where to go, and no place to put her furniture.

Then, the one guy in all the world who cares anything for her and who has given her some semblance of love--at least sex--and a pick up truck, shows up.

Through all of the movie, she has fought against all that is going against her.

Then, at almost the very end, she discovers that Hank is the guy who was head of the prison detail who executed her husband. She is shocked, and you can see her depression building again. Then Hank comes home with ice cream to share. She is destroyed again, but then she looks out at the little cemetery and understands that Hank, too, has suffered horribly. Rather than fighting, she gives into Hanks affection and accepts the ice cream--a symbol that she is ready to start there and rebuild: with Hank.
