How to proceed

Hi everyone, so a friend a mine introduce me to a girl a couple of weeks ago, we went for some drinks(as a group) but we end up talking all night, I took her to her house and that was it. I didn't ask for her phone, but later my friend told me she wanted me to text her or something.
SO two weeks after that we went out again for some drinks as a group, and again we end up talking and I also took her to her house..

the next day I text her, to know if she wanted to get out. She answer me the day after and told me she was a little busy, to what I reply, let me know when you have time. She ask me if all the group was going or only me. I told her only me. now two days have pass and she has not reply. How should I proceed?

I left out a lot of details about those two nights, but my feeling was she was in to me, now Im nos so sure.

Regards hope someone can help me!

why would she want you to text her if she's the one interested? shouldn't she express more interest if she's into you?

If two days have past and you haven't heard from her, I would think it was safe to say she really isn't interested.
