Why is my friend suddenly behaving like this?

Since I moved to my permanent home after fleeing an unsafe living situation, a friend of mine has been acting strangely towards me.

Whenever I share something, she responds with comments like, "Oh, I hope that doesn't happen," whereas she used to be very positive and supportive.

In conversations, she's also said things like, "I’d like to live alone too, but that’s just not possible," ... as if I had willingly left my situation as if it were something pleasant.

I would have preferred things to turn out differently, but I’m incredibly grateful that this opportunity came my way.
I had to wait for years to escape that situation, and now I’m finally living a life without fear, no longer confined to my room without basic daily necessities.
