Irrespective of what your personality type is (whether you're an introvert who needs a lot of alone time or an extrovert who loves being around people), space is an important part of any relationship. When you were living in different countries, space would've probably been the last thing on your minds. The thousands of miles between each other were enough. 

But when you move in together, it can all start to feel overwhelming, especially if one of you enjoys time by themselves on and off. Again, communicate your needs to your partner and find a good balance. Venture out on your own and find hobbies you can do alone. Author of "121 First Dates: How to Succeed at Online Dating, Fall in Love, and Live Happily Ever After" Wendy Newman told Insider that "solo nights" might be a good thing to try. One week your partner goes out for a night out with their friends while you stay in and watch a movie you like, and the next week, you are the one who goes out. "We get a little taste of freedom, and a little re-connection to our solitary self. This brings balance so we don't lose ourselves in the relationship," she explained. 

It is also equally important to spend time with each other — whether that's scheduled date nights or going on walks every other day. Enjoy your well-earned time together.
