Ideally a partnership is a 'the whole is greater than the sum of the parts' situation. It should be a win-win for both partners. If both partners have to 'make sacrifices' then you have a 'the whole is less than the sum of the parts' and in that case, the only reasonable thing to do is to chuck it all out the window and start over.
The 'trial period' in a relationship should be a time frame in which both partners try to figure out if they're in a win-win situation or not.
Incidentally, this is why economic collapse at the societal level leads to so many divorces. Yes, that sounds transactional, but that's the reality of marriage, it's as much an economic partnership as it is an emotional one. Not necessarily a great idea for everyone, too.
