Push and Pull is when you "push and pull" her through different emotional states.Neghits are a good example when you start out good and then "unkowningly bring her down" A more popular and easier technique is the "married couple" one
Ie
U: Wow that lunch looks good did you cook it herself
Her: Yea
U: Just what I'm looking for in a wifey lets get married sweety
Her: LOL *thinking is this guy for real?Does he like me*
U:Wait no I don't like that hairstyle, the wedding is SOO off.
Her: What already? *Why doesn't he like me anymore? Is my hair THAT BAD?* (women, insecure creatures aren't they, lol

)
U: Well you do have good taste in clothing so you can dress me when I go to work and the children will match, that's a must
Her: Haha *thinking "i'm good in his books again*
U: Yea, I'm colorblind so I'd have our kidsd walking around in purple and red... does that match?......
Yo get the idea, this one is soo gold because she also can vizualise a future with you ifyou always talk about the future with her, you are C&F, you are busting her a lot, you are creating rapport, pretty much everything (try and get some kino in their when you make her your wife again
As for qualifying that is when she says things which in her mind our important and show she is desirable or has certain positive characteristics. Also telling stories of escapades or going the extra mile to get your approval
For example after she sees you talking to antoher girl she can say something to you like
Her: Don't you hate it when guys hang off you and you don't want them to? That happens to me ALL THE TIME.
It is pretty lame when someone qualifies themself to you...
