How to not be afraid of settling down?

When I say settling down, I do not mean I am scared of settling into a relationship. I am so so happy with my girlfriend and I want to be with her forever.

My partner and I are both 22, and we got an opportunity to basically own a house. Its crazy and we are so lucky. Im so excited. But this is it. Growing up, I moved CONSTANTLY—Ive never lived in one place more than 5 years, and I like the moving. I love seeing new places, and I love getting to know a new town or city and becoming acquainted with it. My siblings and I all feel the same way—and its not an age thing, considering my siblings are spread out over 20 years in ages and we all feel the same. Moving is natural to us. I always planned on just continuously moving forever.

But my partner wants this to be our forever home. And realistically, if you want to succeed in this kind of society, you really should just pick one place to settle down to get a job and raise children... and its a beautiful home and yard and I should be so excited. And I am excited! But im also mourning how much I know having a house ties you down.

How do you learn to accept settling down as the next necessary step in life?
