This may have been asked several times, but I couldn't find this kind of question, so I'm now asking here.
Is it alright to use past perfect together with when clause?
e.g.) When I stayed in the U.S., Cathy and I had been going together for a year.
Or should I say "When I stayed in the U.S., Cathy and I went together[were going together] for a year."?
The expression "go together" here means "have a date" or "be someone's girlfriend/boyfriend".
It's really complicated for us learners to use perfect tense properly.
Thanks a lot.
"Had been going together for a year" means "We had been a couple (boyfriend/girlfriend or boyfriend/boyfriend or girlfriend/girlfriend) for a year".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
