What do you think of the lyrics I just wrote? (PLEASE ANSWER)?

So I just thought of this chorus that just came to me, and it's about
how I'd fallen out of love with a crush that I thought that I'd really
like, but then he'd stop talking to me. But PLEASE DON'T STEAL THIS I
OWN THIS :) Thanks :) But please tell me what you think :) I'm an 18
year old girl who loves to sing and I really want this as a career. So
I hope you like it :) And here it is. I don't have a name for the song
yet, and I'm just a beginner writer so please don't be to harsh on me.
But I hope you like it :) And I was thinking of calling it "Fallen out
of Love".

When I was young
I never thought I'd fall out of love
It was a rocky way to say good bye
I never thought I'd lose this time
But I always thought that you were mine…
Thought that you were mine

So that's what I have right now, it's just the chorus, but I hope you
like it :) And if you have an idea for a name please let me know :)
I'd really appricate it :) BUT PLEASE DON'T STEAL THE LYRICS :)
