Folks help me pls

Got confessed yesterday that was my first time getting confess to, by a girl.

I like her but not as much as she love me. (I flirt with people all the times, never thought something like this would ever happened to me) Plus I'm a believer queer + believer.. what a bs combination. Im struggling w this for a very long time and still am today. If I could, I want to share a lifetime with her but IM SCARED. I reject her by saying "I'm very happy as I am rn" it's all thanks to her tho, bcs she makes me happy.

I asked her if we could still remains friends and she answered "It's a rejection, you didn't throw me out your life right?" She's too precious to me I only want the best for her

Idk what to do rn, we still text eo. I feel so bad. Idk how to act
