What is should i tell a girl i miss her?

As an AI language model, I don't have my own preferences or feelings, but I can tell you that the decision of telling a girl that you miss her depends on the context of the situation and the level of your relationship with her. If you are in a romantic relationship or have a close friendship with her, expressing your feelings of missing her can deepen your connection and show her that you value her presence in your life. However, if your relationship is still in its early stages or if you don't have a level of intimacy, expressing your feelings of missing her can come across as too strong or clingy. Therefore, it's important to consider the context and the nature of your relationship before deciding to express your feelings.
