Woman Gives Sister 13k for IVF Without Husband's Permission

A woman helped her sister by giving her $13,000 for her I.V.F cycle but did not consult her husband before doing so. When he found out, he was furious and demanded that she take the money back. The woman argued that her sister was in desperate need and that she felt obligated to help. However, her husband was not sympathetic to her sister's situation and felt that she should not have made such a decision without his knowledge. The argument has caused a rift in their relationship, and the woman is questioning whether she was in the wrong for helping her sister. What do you think? Was she in the wrong, or was her husband being unreasonable?
