Ok, so some quick background first. I met a girl through a mutual friend 3-4 months ago. She's a high quality girl, smart, self confident, attractive, good job. I had met her before, but it was very brief. She somewhat remembered, but my hair had grown longer in the meantime, and she complimented me on it. We swapped numbers later.
That was all shortly before the holidays. Both of us are pretty busy, traveled for holidays, then both had relatives staying with us. We've been out together once for a park concert, twice for dinner. I know a lot of you say not to do that, but that's just what I like. I like good food and good restaurants... so it's just me doing what I want.
Since we've both been pretty busy, it's several months between times I've seen her. She knows I date other girls, and I assume she's dating too. (At the least, she surely has no lack of choices, and likely no lack of guys pursuing her.) We keep text contact a few times a week, but it's not real flirty.
So the reason I called this 50 first dates is that so much time elapses between seeing her, it's like starting over every time. I haven't kissed her yet, partially because I know she has some dental issues she is having worked on. (You'd have no idea by looking at her... her smile is pretty much perfect.) I'm not used to moving along so slowly, and I feel like I'm on the verge of friend-zoning myself, if I haven't already.
We wind up at her house at the end of the night. Last night, we're first sitting next to each other with legs touching. (which is fine) Then shortly after, she repositions herself sitting across from me, squarely facing me with upright posture. She's smiling... direct eye contact is pretty much constant. I perceive those as strong IOIs, but she's slightly too far away to touch. (Her moving seemed like an IOD at first, but subsequent body language convinced me otherwise.) She eventually mentions she better get to bed soon, and I say I didn't realize it was so late and need to get going. She says she had fun with me twice (I respond with a 'me too'), she says she'll be around this weekend, and she asks if I'm free this weekend. I pretty much say "maybe."
So now we reach this morning, and she texts me by 9am, thanking me again for dinner and says "I had a wonderful time hanging with you."
The fact that she texted me so soon and the use of the word "wonderful" there sounds like a big green light. "Hanging with you" sounds like she doesn't want to be too forward, but it does seem like we're developing something. Am I reading that right? What would a good response be? What time frame?
