Hi DouDou
Sometimes good girls, get mixed up with bad boys.
Bad boys like bad stuff ....., booze, cocaine, loose women, fast cars, violence.
Good girls like you are just "something to do" between the bad boy stuff.
Sorry to be so blunt, but it's the truth.
Don't fall into 'nurse syndrome' where you think you can fix him and get him to be a good boy.
You won't, he's not.
I hope you can make the right choice for you.
