Mine never shall be parted, bliss or woe. 9:916

Bliss-complete happiness.  Paradise or heaven.

Woe- used to express grief, regret, or distress. 

After Adam explains that he and Eve are joined bone of bone, he tells his final answer to the question of whether or not he will sin.   He says that he will never be parted from her.  This means that he will take the forbidden fruit and sin as well.  It may mean his separation from God, but at least he will be close to Eve and not feel the loss of thee.  He does not want to be apart, but together regardless of Bliss or woe.  Even if they die, at least they will die together.
