i dont have any mind with someone who i dont like.

=> I don't mind someone I didn't like.

i tend to distinguish certinely whether i like someone or i dont like.

=> I tend to distinguish whether if I like someone or not.

that's like a black and white.

=> same as black and white.

so someone who i dont like does never approach me first.

=> So someone whom I doesn't like never approach me first.

therefore i havent been to burn all my bridge with someone who i dont like.

=> Therefore I haven't burn my bridges with someone I don't like.
