You can belong to a place without needing to remain there forever.

Belonging and residence are different things. You can be from somewhere, be shaped by it, keep it in how you speak and what you find funny, and still live your life elsewhere. Treating departure as a betrayal makes people stay in places that no longer fit, or leave and carry guilt for years.

If you have moved or want to, allow both things to be true. Keep the connection deliberately, through visits, contact, and whatever you choose to carry. Going does not cancel where you came from.
