Flirting with me? Interested or am I over analyzing

[super10]

Ok so I kinda started talking to this girl 2 weeks ago. She's in my class and I did t really notice her until the 10th week of school. I'm in college. I met her through her sister and from the point Im not sure if Im getting the right signals.

*she waited for me in the library for 10-15 mins when I was late
I asked her to come study with me in the library but I forgot to mention what floor in the library and her phone number. It's a big library so I figured it was an incomplete invite. I show up anyway and she ended up waiting for me in the front of the library. Extremely nice for someone who doesn't know me.

*mostly talked in the library instead of studying. Tells me if I need any help or anything to ask her. Again really nice for someone who doesn't know me.

*finally got her number while chatting with her for an hour. She was doing homework but when I came to she stopped studying and talked to me instead.

Flirting??
* text her with study guide material that I had cuz I told her I had a good study guide. She textd me back almost immediatly saying "thank you so much!! I owe you one!!" I write back and say " yes you do, I'll think of something " she replied with " oh gosh I'm a little scared now haha"

So I haven't replied since because I do t want to carry conversations via text. But we hardly know each other are these things that I mentioned above point to her being interested or friendly?

Sounds good so far. Now, ask her out for coffee or a drink.

Ask her out...she's interested.
