Hey guys, I was literally thinking the same thing while I was in the shower today (That's where most of my thinking gets done

)and here is my two cents:
What you are talking about are easily mistaken for shit tests.
Now most of us know, Like stated shit tests are to test how much of a man you are. This is her doing stuff to piss you off to see how you react. This allows her to determine if being in a relationship with you is worthwhile. In this case freezeout is to get her into bed with you, as you said, which allows you to go for the relationship.
Now she is already in a relationship with you, so why would she need to shit test you?
You have figured out that responding to these 'shit tests' is damaging your relationship. This is the first step. realizing that:
THE GAME HAS COMPLETELY CHANGED.
Now these 'shit tests' have a completely different meaning. She is no longer testing you as a man. You passed (via freezeout or acting un-phased, indifferent / whatever) , she knows how much of a man you are.
She is testing your love for her. Women need to feel loved. These 'SHIT TESTS' are actually 'LOVE TESTS'.
Women can't help it, bless them. They need to feel this love. It's just how it is, they don't decide it, they can't change it and neither can you. Nothing personal it's just part of this game.
Now imagine if you needed an emotional boost of feeling loved. She's thinking
'OK I guess I know he loves me really, but my fucked up brain is playing tricks and I need some proof'
Cue love test.
Now imagine you are you're girlfriend. You are testing to see if your boyfriend loves you, and instead of reassuring you that he loves you he freezes you out. MAN THAT'S A KICK IN THE TEETH. 'hat basically says, 'You know what I don't really care about you enough to deal with this.' Which inevitably gets interpreted as 'I don't love you'
You'd be pissed right?... How pissed?... pissed enough to have a month of original shit tests prepared to constantly make his life hell right? Now that is going to damage any relationship!
So because you think your manhood is under attack you take offence and try to counter it by using your P.U.A skills acting as if you are responding to a shit test.
The answer to your question and solution to your problem is to be aware that you need to respond to a love test and not a shit test. This should change your frame of mind and allow you to react in a more positive way.
** everything you learn about game does not necessarily transfer directly into a relationship.HENCE WHY THERE IS A SECTION DEDICATED TO RELATIONSHIPS**
Responding to a SHIT test as if it was a LOVE test (which is what AFC's do) = FAIL
but
Responding to a LOVE test as it it were a SHIT test (what you have done) = FAIL
So don't react in a negative way because it will damage your relationship since she will deliberately sabotage it. It goes against everything you think you have learned, since what you have learned is that acting lovingly = AFC and does not fulfils the womans needs. In reality what you are doing is providing her exactly what your woman needs by acting lovingly, acting in a positive way that is reassuring to her. Strengthening her belief that you care for her therefore strengthening the bond between you.
Hope that makes sense. I may have invented the gayest P.U.A term ever with 'LOVE TEST' but it's late and I'm half asleep and it does the job so deal with it!
