I need the suggestions pls

I was in bonding with the girl about last 3years, we slowly became friends and shared each others personal very well. Even I have a feelings to her and sometimes she's also shown interest. At present it was reduced ! Today I have shared some reels to her, its funny reel and bit romantic. she said don't take this things too far its more like emotional connect and I just want to be friends only. I replied that i have no bad intention on you and I'm at my limit hope you have undertand. Later she replied Not interested, give me some space and hope you have understand.

What does it mean? I was not in relationship before and not even I have confessed my feelings to her ! Was I made mistake?
