So i'm 22 and have been dating a 26 year old for about 6 weeks. I genuinely feel that she has long term potential, i have had my share of one night stands/flings so i feel its worth giving a go.
Anyway i've learnt some gaming tactics but truth be told i havnt really gone all out to attract her to begin with. We pretty much naturally clicked. I did keep emotions hidden to an extent though, like when she would ask what i think of her i would give vague answers.

Unfortunately the beta side crept in. Since my ex, i have closed off emotionally from women and just gone with short term flings, but with this one, she created some attachment and i actually now care about keeping her, something ive not felt in a while.
The issue is ive become a bit needy. I also tend to ask her a bit too much about how i think we are going a long, she has basically said the fact that i talk about it so much is killing the excitement about the whole thing. I know, major bad situation.

Before it reaches the end (which it will do at this rate) i need some ideas on how to save it, how to be more unpredictable (like i was in the first 2 or 3 weeks) and how to generate interest and keep her excited about it.
When we are together in person, we actually get on great. We have yet to argue, and often go out drinking either just together or with friends, or just chill and watch a movie and have some food. The sex is also incredible, she is ALWAYS up for it, and we go at it like i havnt done so much with anyone else! The issues tend to be when we are apart, i will strike up convo over text about how we are going, and generally just become needy and worry somewhat when she goes on nights out etc.

So any advice would be great.

Dude, you know what you're doing wrong. All you have to do is stop. If you don't she will slowly push you away, or take advantage of you if she isn't nice.

Have you ever been with a girl that starts getting needy and jealous? Remember how that changed your perception of the person doing it? Don't be that person, but yeah easier said than done I know. Try visualising your behaviour but with you being the victim of the needy behaviour. That normally helps me when I get the urge.
