Because I always get confused of it, should I use would have if I am talking about something that could happen because of what someone did? For example:
If you told her, you would have seen the play. And if you didn't you would probably have seen it.
And should I also use it if I am telling a story about my fast and there is something that could also happen in the future but i expect to happen in the past. For example:
When I was a kid anything I expected would have happen and if I didn't it wouldn't have.
