If this is the Romantic era, consider if he is really saying that disclosing how one feels toward a young woman is bad?

This poem is a departure from Blake’s' usual meditations on lost innocence and religious restraint on the human soul. The speaker has been spurned by proclaiming his love to another person. The speaker then explores the freedoms one experiences by not being in love: freedom from jealousy, freedom from admiration and affection, freedom from desire, and freedom from want. Blake’s final message is “Never pain to tell thy love” or spare yourself the pain of declaring your love to another.
