Louise sees her future self telling her daughter that she knows something about a forthcoming 'unstoppable' disease and Louise's husband (the child's father) left her when she revealed this to him. She said that he believes she made the wrong choice in some way related to this.
This fact did not seem to be referenced further in the movie. What was this about? Am I failing to read between the lines? Is this her saying that she's going to develop a disease or is the disease the thing the aliens want humanity's help with in 3,000 years?
Was he mad because she knew she had a disease and didn't tell him before they had a baby, so maybe he and their daughter were also infected? It said that the father didn't look at the daughter the same way after he learned about this disease...
