7. You have totally different lifestyles.
If you like eating multi-layered sandwiches for breakfast and don’t like jogging in the morning (or any time of the day) while your new partner is obsessed with superfoods and goes to the gym 7 times per week, it’s unlikely you’ll be able to build a harmonious relationship. The same story applies to homebodies and avid travelers; modest workers and those who like to party hard; and pathological cleaners and those who like to eat cookies in bed.
A vastly different attitude toward leisure and everyday life quickly turns love into hostility, sometimes even disgust. It doesn’t mean that you or your partner are bad. It means that initially, your paths shouldn’t have crossed and you didn’t realize it at the very beginning.
But this doesn’t mean that you should seek your potential partner among people with the exact same habits and tastes — finding common opinions regarding your general lifestyle will be enough.
