"The Flea"

I felt "The Flea" was about a couple who couldn't be together because their families were enemies.  The woman refused to marry this man for that reason.  "The Flea" resembles her pregnancy.  The woman doesn't know what to do because she knows her family won't accept the man or the baby, so she decides to kill herself, which causes the baby to also die.  The man states this as "three sins in killing three". It sounds like at the end when the man states "[T]his flea's death took life from thee", the man is blaming the baby for killing the love of his life.  This poem reminded me of Romeo and Juliet, taking the fact they couldn't be together because of their families.
