Not agreeing on the place
This may happen, and it’s hard: one of you falls head over heels in love with a place and the other does not want to live there. That’s painful. You need to find a place you both love. That’s what you agreed on. But you feel your partner is being close-minded or stubborn, and forcing you to say goodbye to a place you could see yourself being happy in. Resentment can run high.
