Confused

I remember the day I met u 
You were smart
Funny and a great guy
We got to know each other 
Hang out n had fun
Then one thing happened that changed the way u thought bout me
That was the worst mistake ever for me 
Maybe there was a real relationship going to happened but I just need more time to think
Who ever knew 
Now I have lost the most important friendship I could ever ask.
Cause u made me feel like I could be myself n nothing couldever happen to me 
I know wat I have done was stupid 
N I regret it so much 
I hope you understand this cause I'm just saying what I feel
