If you're the one doing all the chasing, then you're the one making all the investments.
You come off as being needy...
BUT... when the girl is chasing you then SHE is making investments... which will create value.
Girls want to feel like you're worthwhile, so when they have to put in some effort, they're going to try harder to be with you.
Anything worthwhile takes effort... it's going to be a bit challenging.
I STILL do things to make my Fiancee chase me.
That keeps her interested.
YES, when you're in a committed relationship, you still have to "play the game".
Sometimes I'll notice that she acts less interested in me, and that's when I realize I'm doing too much, as far as "chasing her" goes.
So, I'll back off a bit & show her negative body language. (sit further away from her; face away from her; not touch her as much.... almost like I'm being slightly distant.)
When that happens, it triggers an emotional response in her, because it's not like my usual self... and it causes her to start chasing me & making more investments again.
Sounds kinda cruel right? But it's not.
It's a psychological principle that works with MANY situations.
The more someone puts into something, the more value it has to them. The harder they have to work at something, the more important it's going to be to them. (Including relationships).
It's important to keep doing the little things you did when you first met a girl... (Flirting/teasing/bantering/building attraction).
Don't be needy or clingy. Don't be afraid to take a step back & let her "chase you / come to you" at times.
It's part of relationship balance.
If a girl thinks you're gonna work your ass off & bend over backwards for her with everything, she's gonna get bored with you. You're going to be the "beta male".
I'm NOT saying you should be an arrogant jerk. I'm not saying you should be domineering...
I AM saying, you need to be Alpha... be confident & show dominance.
Don't be pushy OR a push-over. Have your own opinions & interests.
Now, when you DO have her chasing you, be sure to reward her with positive attention & reactions. Otherwise she'll get tired of chasing you altogether & you'll screw it up & lose her.
So when she starts hanging on you, touching you, kissing you, etc.. do NOT ignore her. Show her affection by reciprocating the same actions. This will make her more likely to initiate physical & intimate contact more frequently.
It's really simple, so don't over-think it.
Don't give too much... but at the same time, don't give too little.
