Girlfriend (26f) told me (33m) she wants to move out

We’ve been together for just over 2 years now and lived together for 1. She told me this weekend that she doesn’t feel like herself and wants to live independently for a bit. She said she’s never lived alone and thinks it’ll be good for her and our relationship because we’re both always busy and default to staying in and relaxing at home. Not living together would force us to spend more intentional time together. I feel like this is the beginning of the end, am I crazy to feel that way?
