So I met this girl from online gaming yesterday who I immediately developed a bit of oneitis for. We met in the city and then took a walk to a sushi place, we ate, then got lost in the city and ended up watching a movie, afterwards we walked to the train (we take the same train home but she lives a few stops later).
Some notes:
I payed for the food and movies (I didn´t really give her the option to pay for her part though, and I make a lot more than she does)
I talked a bit more (she admitted she was shy, but she laughed a lot and we held hands when walking)
Kissed a couple of times in the movies, but I escalated pretty slow
Before we met, she had been texting me a lot but now afterwards I feel that she is a bit short with me on her texts, so I want to hear your guys opinion on this. This is the first girl I like for about a year now so I am more invested than I usually am in this.
Texting after the first date:
She starts three hours later: Thank you again for today, was really fun

studying hard now?

me: Taking a nap + reading some psychics.. Yes looking forward to meeting you again

how´s the math
her: Just had dinner so gonna read more now

me: Hope it wasn´t sushi
her: haha no it wasnt

but i made my mom promise me to make sushi soon

me: haha that´s awesome, you might very well be a genius (heart emoticon)
her: haha maybe

me:

her: gonna go clubbing tonight?

me: Nah, need to study, you gonna try to sneak in? (she´s not 18 yet)
her: Totally

and also gonna try and get free drinks haha but no i need to study maths

me: Noo don´t become a clubbing chick:(
her: I wont haha dont worry

me: Naw that´s my rebel angel (heart emoticon) ( inside joke)
her: hehe

me:
one day later (tonight):
me: If the weather cooperates, have picnick with me on Thurday or Friday for lunch?:)
her: Sure

friday would be the best:)
me: Friday it is, good luck on tomorrow´s test :*
her: Thank you! :*
her again: How are you today?:)
me: Sick of studying, little disappointed in myself since I´m taking a week of form work. Otherwise happy:) you?
her: Aw dont feel disappointed

im good, been doing maths for the whole day so hopefully will do good on the test tomorrow
me: I'm sure you will

throw in some string theory if you wanna sound extra smart:)
Her: haha ill try:P
me: Then I´m sure you'll do great, try get some good night sleep:)
her: hope so

yeh im actually gonna go and sleep now, goodnight:)
me: goodnight:)
Compared to before, she writes shorter texts to me and she has never been the one to end the conversation (I always did, we texted for like a week before meeting). So I´d appreciate any feed back or general thoughts please:) I´m a little dissapointed that she didn´t reply with heart emoticons when I used them. Shes 17, Im 18.
