Good advice from Howell, although he is taking somewhat of a fatalistic approach (you might just not be right for each other, or she might be in a very experimental phase etc -- these are factors you cannot control, so if that's the issue you might just have to roll with it).
However I can say that IF you get a solid process down and do things right from the start, the course of the relationship seems quite predictable in my (admittedy limited) experience. Although lots can go wrong, girls are quite good at screening, so chances are that if she slept with you and you didn't fuck anything up, she wants to take it further (we call this post-sex retention). In that case it will be a fairly typical "FWB, spends 3+ months trying to tie you down into a relationship, is either happy with what progress she sees or auto-rejects and leaves" type deal.
Sure, there are exceptions. Like check radeng's journal "HB oneitis". In that case SHE wouldn't commit and left him a bit puzzled and upset as the months rolled by. But that's pretty rare. 95% likely, if this is not the pattern you see, you fucked up somewhere -- could easily have been before you even bedded her (setting too much of a boyfriend/not lover frame, for example)... in fact even in the difficult case I mentioned, radeng thinks this might have been an issue to some extent (radeng: correct me if I am wrong).
So, in my opinion you should be trying to troubleshoot your game. Anyway, experience is the best teacher so if there is any issue with your dating process or relationship management it will surely show up when you date more girls. It does sound like in your case it might be game over with this particular girl, but not NECESSARILY because if you can troubleshoot your issue you may be able to recover, depending on how bad it is.
For example, failing a woman's test is losing a battle and she will then test you much harder next time, but you can still win the war. My girlfriend tests me CONSTANTLY and that is one reason why we have a good relationship, because I dismiss her tests NEARLY every time and thus build a lot of attraction.
I highly recommend you read Franco Seduction's book titled "Manual of Seduction" (not the Franco from these boards) for more information about women's tests. You are being tested every day, whether you are aware of it or not. Here is an example of a test my girlfriend gave me a few days ago:
her: lately sex has been very difficult for me, I really tried hard to enjoy it but it hasn't worked [I am thinking WTF she is a horny little bitch who demands sex 3 times a day, gotta be a test]
me: oh really?
her: it's because I'n pregnant [yes she is 4mths pregnant to me], pregnant women have a drop in sex drive in the first X months
me: news to me, I am pretty sure it is case by case
her: no it is true
me: where did you read or hear this?
her: everybody says so [yep -- it's a test]
me: so you can't orgasm right now?
her: that's right [she looks really sad, I am flabbergasted she would think I'd fall for this bullshit, I give her orgasms every day]
me: I see [I kiss her and start to nuzzle her neck]
her: mmmmmnnnhh [sighs]
me: [I move down and start kissing her belly, her legs, around her panties etc]
her: [puts her hand over her pussy]
me: [continues to escalate, gently removes her hand, her shorts, her panties, etc]
her: mmmmmnnhh [starts to moan, breathe heavily, rock her hips etc]
me: yes, I agree... nothing seems to be working... what can we do?
her: [giggles]
TEST PASSED... WE HAVE AMAZING SEX
Hopefully this gives an idea what I mean. I can also see some other potential issues:
I make her feel accepted and valued by listening to her worries and problems and I make her feel accepted and valued by giving her compliments.
This has to be done very judiciously, and only as a reward for her investment and compliance. If you are not an experienced seducer you are probably being an emotional tampon and supplicating to her beauty. Cut this out completely until things are on a more solid footing. Practice some rejoinders "do I look like a psychiatrist?!" / "I haf diagnose you wif zee penis envy" or if she asks for praise "don't worry, fat is the new black" etc.
I also feel you do not have sufficient abundance and she can sense this. Despite your being in a relationship I recommend you set yourself some cold approaching goals and grab some dates and numbers. You don't actually have to cheat, if you meet a girl you really click with and set up a date you can always call your girl and break up with her before the date.
Another thing that I suggest you do is to cold approach and flirt with a few girls while you are out with your girlfriend. For example you are walking along the street with your girl and you see a woman dressed in smart clothes, you say "Hey! I noticed you walking by and I HAD to compliment you on your outfit... you are going to lunch now? Or it's a meeting?" ... fluff talk a few lines and wish her a good day. This signals to your gf that she is replaceable. BUT, use this technique VERY SPARINGLY. Chase says ONCE per girlfriend is enough. With experience you can do it more, and more casually, if you wish.
