Let’s say I know my friend has broken up with his girlfriend. I don’t know when, but I know he has. I want to know whether or not he’s given her brother an explanation. What should I ask?
Have you explained to him why you broke up with his sister?
Have you explained to him why you have broken up with his sister?
Have you explained to him why you had broken up with his sister?
My gut tells me it’s the last one, but the more I think about it, the more confused I get. I think I should use “had broken up”, because the breakup had occurred before my friend would’ve had a chance to tell his girlfriend’s brother about it. Is it important in this particular case? have broken up also seems ok-ish to me, but I think I should use past perfect to show the correct order of what’s happened. broke up seems completely wrong as I don’t know when they broke up.
