Let's say your bestfriend and his girlfriend has finally decided to marry each other. Knowing that, you now ask them if they talked the marriage through, and you say:
Have you guys talked this through before you made that decision.
Or
Have you guys talked this through before you made that decision.
From my research, as for the sequence of events, the present perfect tense comes first and then the past tense if the situation is still happening right? But should I add HAD(from sentence#2) or not?
