Your cracked

Your cerebrum must be cracked, 

From the chemical smoke stacks which induce memory lapse of when I had your back. 
Soaked my heart's gash in a mineral bath,

 In relationships took aves I shouldn't have. 
Received no rewards for bending over backwards. 
Relieved myself from everybody else just to protect himself. 

The tweet not, cheat not , Cosmonaut. 
Whose love never stop, 
Even when faced with the tears of a croc.
