Porphyria's Lover 

by Robert Browning

"Porphyria worshipped me; surprise 

Made my heart sweel, and still it grew"

True love make people lose their minds, and perhaps, this crazy feeling can lead to obssesion and dependency. Also, love make people do crazy things that later they might regret. This poem seems to be pretty dark, for the love described it follows a dark path. The men seems to be obesssed with her that even when she is dead he performed inimaginable acts with her. This poem, I consider, shows the fact that loving can lead to madness, and for some this madness is understood as true love.
