"Is the reason WHY you don't want to be friend with your cousin because you are holding a a grudge with him, or because you dont have anything in common?

Answer 1

Comma before the 'or' , no 'why', but other changes are needed:

Is the reason you don't want to be a friend to
[or 'to be friends with' - idiomatic] your cousin because you are holding a grudge against him, or because you don't have anything in common?

Answer 2

I would write, "Is the reason you don't want to be friends with your cousin because you are holding a grudge against him or because you don't have anything in common."

no comma before "or".

Answer 3

i could write, "Is the reason you do no longer choose to be associates at the same time with your cousin considering you're conserving a grudge against him or considering you haven't any longer something in difficulty-loose." no comma till now "or".
