4. Pass or Fail
Last, but not least, moving in together is the ultimate test. You either adapt to each other’s routines or find that your lifestyles are just too different. Though you'll both be faced with a new set of challenges, you're at least taking the next step and learning whether you're really compatible. If you're still positive about the relationship after moving in, congrats! If not, it's better to find out sooner than later.
