what is the plot resolution in Enrique's Journey ?

I believe the plot resolution occurs when Enrique and his mother are reunited. The two believe their reunion will result in what they've dreamed about, but all too soon reality sets in. Enrique cannot find it within himself to appreciate the sacrifices his mother made for him, and he in turn, is disappointed. He turns to drugs and alcohol to ease his feelings; she resents his withholding of respect. It becomes a vicious circle.
