My girl says the spark between us is gone. Anything I can do to get it back? Any techniques or plans?

Have you read The Game? If not, read it.

In the book Strauss talks about relationships that lose their spark and the reasons why. Blokes can become too needy, are too nice, pay for everything, get jealous when their girl is talking to another bloke, bend over backwards to do things for her. They basically make it too easy for her which causes her to lose interest.
(I can relate to some of those points from previous failed relationships).

You need to work on youself before you can work on her. Learn to open groups of people or girls up (Mystery Method) - but not necessarily with the intent of picking up girls. Learn how to get people interested in you, think of stories, learn one or two bar tricks.

...TBH I'm pretty sure you'll meet someone better whilst doing this anyway and sack her off completely...

I'm aware of these Do's and Don'ts, and have employed them in this relationship. However the spark still managed to disappear somehow, I must have messed up.

Read David D's book, he's the best and can help. You have to flirt a lot with her, to be playful, to tease her and the spark will come back. Visit also this site http://seduceandattract.blogspot.com/, because it contains a lot of great ideas, how you could improve and bring that spark back.

Thanks but the link appears to be broken.

Oh nevermind, thanks!

First PUA, is not something you can learn in two days by reading the game and going to relationship department, and bam Neil Straus gives the answer “What to do in this situation"

Relationship is a lot different than gaming girls. She is giving an excuse in space of weeks or months kick in your ass. Believe me going out, while you are in relationship and gaming other girls that will solve your problem. Maybe you will find another girl , but i think that not your objective.
What she is telling with “we lost our spark “is :you are boring, we spend too much time together. I m attracted to other guys, I have you on the palm of my hand, you are my boy toy lolol.
You should in my opinion.

- Don’t know if you have hobby but you should. Krav Maga , art school… I don’t know something you like.

-Give her more space, don’t try to push or forced things,(yeah i know she said you lost your spark) , and your immediate response is to suffocate her, because that how human worked, if we are holding something, and we are losing, our response is hold tighter in this case do exactly the opposite.

- Be romantic (spontaneous) something she is not use, completely different, there are a lot of ideias on the net if you look.

- Dont be needy or jealousy. BE CONFIDENT BE A MAN, there alot of threads sticky explain what the best way. There are a lot of threads about inner game also. Its really important you should read it.

-You can read what there are saying, maybe it will give you the confidence, she will pick it up, and more important, her friends will pick, and you will be more attractive simply because HER FRIENDS THINK YOU ARE HOT.
-Week has 7 days so being together 3 days(ofc it depends) is enough, THIS GIRLS NEED TO START MISSING you, wondering what are you doing and if you have other ladies.

-Try new thins on the bed department. There are a lot of good reading material here on how “ to FUCK GOOD A WOMEN.
