You dig each other, no reason to play games.
Dude just make her feel special you need to transition from this PUA stuff into relationship mode if that's what you want with this girl. Plan some romantic things for the 2 of you, but be a bit mysterious, never lay all your cards out as predictability gets boring - even for a chick who's really feeling you.
If you're having problems finding unique places to take her to checkout a tourism page for your city/town. Also, a lot of girls just like to stay at home with their guy and cuddle watching a movie. I wouldn't text her all the time to be honest otherwise when you meet you have less to talk about and also it's important to have autonomy in any relationship; being in each others' 'face' all the time gets annoying quick - think of it as a star expending its energy at a rapid rate, it'll just supernova quicker, so learn to slow things down a bit as it creates great sexual tension and will leave her longing for more, and also help you keep control of things. I'd still use a bit of push/pull with her but ONLY as a tool for escalating sexual tension (makes for much better sex).
I think you need to look back on this and take inventory of what you did right. Obviously it got you this far with her, so perhaps only minor tweaking is necessary.
With respect to text whoring each other - IT MAY FEEL GOOD TO HAVE ALL THIS ATTENTION (studies show that whenever we receive a text or even a FB poke, msg we experience little squirts of dopamine in our brains - the 'feel good'/reward neurotransmitter), BUT IT SUBCONSCIOUSLY TELLS THE OTHER PERSON THAT YOU'RE ALWAYS AVAILABLE/ACCESSIBLE. This is actually a form of intermittent reinforcement, if you'd like to read on it you can do so here

Things you can do: Drive-in movie (bring a blanket, some food even), take her to a really cool/unique restaurant, ice/roller skating, drive somewhere to outskirts of city with beautiful view, take blanket and lay on beach with her at night under the stars, go somewhere and bring her favorite dessert with you as a surprise, shooting range, go-karting, arcade, bowling, amusement park, haunted house (it's Halloween, must be some in your area) etc...
Figure out what her interests are and plan things things accordingly. With chicks its the little things you do that really matter - anyone can do the above things, but really if you aren't in the moment with her, and engaging her it wont matter, so above all else do something to quell your anxieties (e.g. think to yourself she likes you so a lot of the work is done and now you can just enjoy her). You can also "fake it till you make it" - in other words think what a confidant man would do, and act this way. Big mistake would be to act ON all the time, you might annoy her so if anything be a bit more on the chill side, and if she's worth having around she'll like you for who you are.
