I love this movie. Although, I've always thought that the aliens gave her the gift of seeing the future, and even knowing how her daughter from the future would end up and knowing she was going to meet the father at that time, she wanted to take the risk of experiencing love and living the short time her daughter would spend with her. Anyone who knew the future knowing that the relationship was going to end and her daughter was going to die, would not have wanted to go through with it. Not her, she took the plunge.
