Let’s take a look at the Korean sentence pattern Verb + 면 됐다. We use this to assure someone that we are not mad, worried, or sad anymore because it turned out just fine. At least he did something that lessens the tension or negative feeling. For example, it was 10 o'clock, but strangely my son was not home yet. His phone was out of reach and my text messages remained unread. Ten minutes later, I got a call from an unknown number. It was him. He apologized and explained what happened. I felt relieved that he called. To assure him that I wasn’t mad, I said That’s okay. At least you called. The main verb is 전화하다 (to call). Its past tense form is 전화했다. We take the verb stem and attach 으면. Then, we add 됐다. The actual sentence is 전화했으면 됐어.

얘기 안 했으면 됐어.

I am mad that you told him about our conversation, but I am glad that you spared that part.

전화했으면 됐어.

I broke down because I didn't know where you were, but now that you called, at least I know you're safe.

안 먹었으면 됐어.

I thought you ate my food. Now that you told me you just keep it in the fridge, I feel relieved.
