Is it permissible for a girl to talk to a young man who works with her in the same school and proposed to marry her, but she rejected him? Then she wanted to talk to him to inform him that the rejection was not due to religion or morals, but rather due to a mismatch in personalities because of the stress she was experiencing on Messenger. They then discussed the reasons, and she informed him of his ability to change, and they agreed to postpone the matter for a while until he proves the change. He then sent her a message saying he was ready and wanted to talk to her family, but she refused for the time being until he proves the change more. After a month, she saw something of his on Facebook that she didn't like and found very annoying, so she wanted to alert him about it. Then he opened a conversation with her about proposing to her family, but she preferred to postpone it to complete the first appointment. What is the ruling in Islamic law, knowing that they do not mix at all in school, and they are both teachers, and their conversation was never romantic, only about the proposal and its obstacles? She knows her father rejects certain things about him, so she wanted him to propose, and he is ready. What is the ruling?
