You're doing the right thing - taking it one day at a time.
As soon as a girl starts to "lean away" from you (physically or emotionally) then you MUST do the same thing. If you lean INTO her when she's leaning away, you'll only come across as needy or desperate.
The best thing to do is give her the gift of missing you. If she doesn't come back to you, that means she was never really that interested. Trust me, if she's interested she'll show up at your door.
And the last thing you want to do is to "TALK" with her to make things right. This is like leaning into her. It says "hey, I feel nervous and uncertain and I'm not MAN enough to handle these feelings... so can we talk about it so that I can feel better?" This will push her way.
Don't talk. Just LEAD. Take action and lead. If you like her, then invite her out with you. Invite her to join you in some non-date scenario. Then, over many dates, escalate. Don't be afraid because you've already kissed her. You just need to remind her body how good it feels when spending time with you.
If she avoids you then let her go. Don't be needy, just be glad you had the time you had with her, then move on. Don't get jaded or hurt, because she has her own things going on that has lead her there.
Best of luck man!
