Is it permissible to marry a girl who reveals her marital secrets to her mother, and is her excessive sensitivity considered an impediment to the stability of married life?

Praise Allah for blessing you with a righteous wife. What you complain of concerning her can be remedied through understanding, admonition, and gentleness, for the Prophet, peace and blessings be upon him, said: "No believing man should hate a believing woman; if he dislikes one of her characteristics, he will be pleased with another." And women were created from a crooked rib. The wife must refrain from divulging marital secrets, for divulging a secret is forbidden by Islamic law, and obeying her husband is more incumbent upon her than obeying her parents. The wife should not involve a third party in her marital disputes except out of necessity. As for her quick emotional reaction and crying, she is not to be blamed for it, and she should try to control her emotions with the cooperation of her husband.
