im have having second thoughts on the ending..

ive always appreciated the ending of la la land until recently. i don't see how mia and seb couldn't have made it work. if they love each other so much, wouldn't they have been able to make accommodations or work out something for them to still remain together while they're achieving their dreams??? i mean yeah it mightve been difficult but doesn't that difficultly make the ending of them being able to achieve their dreams together so much better???? i can't imagine having to live with that "what if" feeling. i think they would've been so much happier with one another.
