Love Addicts: A Never Ending Circle

Why do we do this to ourselves?
 
Is it an undying love for eachother?
 
Or an obligation?
 
Is it thinking we will find no other?
 
Or a fearful hesitation?
 
Words are said like, "I'll face all dangers, in any nation."
 
Hurtful words are said in anger and frustration.  
 
We always relapse and swear a vow of dedication.
 
Then make the other's heart collapse, to the need of respiration.  
 
I'm brought back to life by that same infatuation.
 
Then without an explanation.
 
One touch, I'm over taken by the warm sensation.
 
An ever lasting temptation.  
 
One more time, I'm taken by your captivation.  
 
One more time, we become an unstoppable combination.
 
But is it just an act of desperation?
 
Are we just setting ourselves up for devastation?
 
Contradicting thoughts provoke the contemplation.
 
why do we do this to ourselves?
 
Is it an undying love for each other?
 
Or an obligation?
