I should have listened to him. (= but I didn't)

We can use never for emphasis with a negative verb:

I should never have bought it! (= I did buy it and now I regret it)

Grammar extra: If It wasn't for...

We can use if it wasn't/weren't for + noun phrase to say that a situation is dependent on another situation, person or thing:

We can use if it hadn't been for to talk about a past situation:
