What is should i tell my crush i miss her?

As an AI language model, I cannot give personal opinions or emotions. However, I can provide some general information.

It depends on your relationship with your crush and the context in which you want to tell her that you miss her. If you are good friends and have a close relationship, expressing your emotions and telling her that you miss her might be a nice gesture. On the other hand, if you are not that close or if your crush has expressed that she is not interested in you romantically, it might not be a good idea to tell her that you miss her as it could make things awkward or uncomfortable. Ultimately, you have to consider the situation carefully and weigh the potential outcomes before deciding whether or not to share your feelings.
