Don't say it, if you don't want to.
You don't have to say it, if you don't want to.
How do I convey these in Japanese correctly?
My idea is 言えないこと言ってないもいいです。
But I am really confused by verb conjugation here.
Don't say it = iwanai? ienai?
Don't want to say = ienai? But then it would mean 'I can't say'....
Could you please help in both translation and explanation for these two conjugation forms.
