Why does she care if I delete her number?

[New Guy]

So this coworker I was talking to for about a month deleted me from instagram after I deleted her from Snap Chat. I only deleted Her from snap chat because I think she got the wrong idea from all the snap chats I send her and the rest of my friends. She texted me a paragraph saying we were nothing more than friends and she had no intentions of being more. I said "haha same here. I'll stop texting if it bothers you though". She said No, it doesn't bother me. You're good." And we left it at that.
I deleted her number which deleted her from Snap Chat. A few days later she deleted me from Instagram.
Why if she just wanted to be friends?

She most likely likes you and was "upset" that you deleted her from that social cite. So, to see if you notice, she deleted you from another social website. I would just leave it be and not bother texting her anymore; especially if you not interested.

She likes you, but she is not sure of starting something with you. Let it be.

she cares about you that's why ask her on a date
