Interesting read Morpheus and an interesting night.
1. Will these little micro give a fuck thoughts be there forever?
Before you were worried about the 'macro' give a fuck thoughts.
Now they are fading you are left with being able to have more visibility of the micro ones, which at some point you did not notice with all the macro ones in the way.
The process will continue.
Smaller and smaller 'give a fuck thoughts' will come into your awareness as the bigger ones are dealt with and fade away.
It is up to you when you reach a point where you are happy with where you are.
To some level some may always be there, they may just be at a point where they do not bother you or impede on you in any way. It is an ongoing process.
Think of it like sound or something similar.. Before you could not hear the quiet small sounds because of the big 'boooms' that were going off all around you. As you deal with them and they fade, you can hear quieter and quieter sounds. At some point you will have some background noise that does not impeded on your consciousness and is just there.
Which means the more attracted she is the less she pays attention to your actual state and pays more attention to the box she thinks you fit in. Kinda like how guys do that to girls.
Very much so. 
An important realization that will make sense of a lot more if you think about it.
--
As you have seen, reducing the background noise in your thoughts and actions allows you to observe more about yourself and your reactions/thoughts. The same is true of observing others, it allows you to see others more clearly.
This together with introspection and observing yourself teaches you not only about yourself also about others. As much as we talk about the differences between us all and the differences between men and women there are a lot of similarities. The more you learn about yourself, if you are paying attention, the more you also learn about others.
