Whyd she ask me if i had a crush on her?

Basically I tried to be friend this chick at my local pet store.
I gave her a present for her birthday, Would text her and popped in just to see her. One time gave her pills for her flu, we became online mates for 1 year ish. I came out on Instagram probably half a year ago or something. Basically, we were discussing online dating apps, and she asked me a question. She said the following- 
Hey I don't want to make you uncomfortable, I am a very open and non judgey person.. Gotta ask though as I always wondered.. Did you have a crush on me back when we first met at (name), and you bought me those cool gifts for my birthday? Sorry if that makes you feel awkward! I don't mind whatever the answer is!Just curious! 
Why'd she ask me ? 

I asked her the same question and she said the following: 

Her- Haha fair enough, equivalent enchange of answers is only fair! I thought you were a super lovely and cool person, but I was early days in a relationship and very in love so wasn't really thinking about anyone but that person! So no didn't have a crush on ya sorry! Thought of you as a great friend, always a laugh and enjoyed talking to ya. 

Also, I made a post in a girl advice group asking why do people always leave me on seen and how it's annoying and hurtful. Later I was chatting to her online and she said hey random question but I am not the one u were talking about in that group was I? So she was feeling worried because we are friends or because she secretly likes me?
