Idk but im sorry

I dont understand what just happen.  
Other then the fact we just had this unplanned argument  
Some wea we crossed paths and our blue skies  
Are gloom.Im left puzzled standing in wow  
I can't remember what was said but I lost it all  
My happiness, my santuary, your kind heart.  
Its like we started a race and I didn't hear on your mark get set go  
But you finished the race and left me to stay  
Lines got crossed and my universe slipped away  
I wanna just plea I'm sorry and I hope it becomes enuff  
I'm scared of what just happened.Guess I'm not so tuff  
I'm trying to understand the wat happen  
That made us have this change of heart  
Baby can we start ova from the beginning this time with calmer hearts.
