A young girl and boy had a relationship during their teenage years that lasted five years. The girl suffered from a chronic illness due to the boy, which negatively impacted her life. After realizing the wrongness of their relationship, they considered distancing themselves, especially since the girl's father is alive and they cannot perform a temporary marriage contract. They attempted to separate multiple times, but the girl is so attached to the boy that she has harmed herself and ended up in the hospital several times. Her physical and mental health is deteriorating day by day unless she speaks with the boy, which helps her gradually. They are now in a difficult situation where they cannot stay together, but the boy's absence negatively affects her life and exacerbates her chronic illness. Is it permissible to have a temporary marriage contract without her father's knowledge, solely to avoid harming her? Since the temporary contract could be the reason for alleviating her psychological and physical suffering. If it is not permissible, which references allow marriage without the guardian's consent in such a sensitive case due to her chronic illness?
