Don't say it, if you dont 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.
