Do you want to know when to use should have, could have, and would have? Check this post and find out.
Could have means that something was possible in the past, but it did not happen.
Ex: I could have gone directly to college, but I decided to travel for a year.
Would have is a bit more difficult because it has two common structures. The first is with but. I would have A, but I had to B. Use this structure to show that you wanted to do something in the past, but you could not.
Ex: I would have called, but there was no phone service.
Would have also forms the result clause of a past unreal conditional.
Ex: If I had known they were vegetarians, I would have made a salad.
Should have means that something did not happen, but we wish it had happened. We use should have to talk about past mistakes.
Ex: “I was so worried about you. You should have called!”
