Very long post: Is she leading me on or just hesitating out of fear and shock?

Alright, so I've recently met this one girl in my class after she was put in my group to work on a project with me, I see her twice time a week at my uni. I've known her for about 1.5 months now and through out this duration, we connected well and started off with consistently having deeply personal conversations for hours.

As time went by, this progressed to frequent flirting where she'd do the following every week: follow me around campus for the day, offer to share some food, she stares and focuses all her attention on me when I talk and looks irritated if any other guy interrupts our conversation, she'd playfully sneak up on me and be playful.

More recently, she would mention on a few occasions about how she really enjoys working with me because I make her feel good and always make our conversations interesting. Then we had a conversation about what personality qualities we're into dating and the qualities she listed all matched my personality.

This has caught the attention of other women in my group as they have said that they believe she is flirting with me and has interest, and have asked if we were dating.

After all this, I had decided to boldly straight up ask them out. From their response, the seemed mildly shocked but in a positive way because they were smiling. They had said the following: "Can I think about it?" I nonchalantly say "ya sure." After some silence, she then asks why I asked her out, and I gave my 1 min explanation and we go about our day like nothing happened and I now reduce my attention a bit as I perceive this interaction as a rejection and that she must not be interested.

Fast forward next day, the day goes by like usual but towards the ending of the day as she heads home she tells me she'll have an answer next week when she sees me again (ok? lmao).

I don't know what is happening, I have one friend saying that she's just leading me on and to not date her if she makes her mind up and says yes, while some other friends say she's shocked.
