How did you feel when you read Helena's decision to tell Demetrius about Hermia and Lysander's plan?

I feel sad and sorry for Helena because she is somehow hopeful that by telling Demetrius of Hermia and Lysander’s plan to elope, Demetrius will eventually give up his love for Hermia. Helena was wrong because Demetrius decided to chase Hermia and she is left with a choice to chase the love she had lost to Hermia.
