One archetype that can be found in Shakespeare's "A Midsummer Night's Dream" is: the lover.
The character of Helena is a lovesick young woman who is desperately in love with Demetrius. She is a jealous, and insecure woman and is devoted to Demetrius despite of knowing about his flaws.
When Demetrius choses Hermia she devices a plan to break them up by telling him about the plan of Lysander and Hermia to elope into the forest.
