Could someone help me explaining this sentence? Thanks

Hello, I have a bit of trouble understanding this sentence. Of course, I understand the words, but I have a bit of trouble with putting it in the right context. Could someone help me out? Thank you, I appreciate it very much!

Если написать человеку, который к тебе равнодушен, что он тебе нравится, что без его общения тяжело, это будет глупо?

Would it be stupid to write to a person, who is indifferent to you, that you like him and that it is hard without communicating to him?

Thank you it-ogo! I appreciate it:)
