Why would a friends with benefits (female) keep texting me everyday even when I try to end the convo?

She said she's not looking for a relationship but then proceeds to text me EVERY SINGLE day asking "how my day was", "if I got home safely", "what I am doing", "wishing me a good day", and even to the point where send sent me a heart emoji (which is the first time she sent an emoji) and called me "babe" at one point. Every time I try to end the chat purposely, she would reach back out the following day. It's so confusing to me.
