Having a neet gf only makes you revert from neet-ness

He wasn't always a NEET. He's this guy: https://neetpride.wordpress.com/2019/02/18/my-rapid-disillusionment-with-and-rejection-of-modern-day-wage-slavery/
The two NEETs would fail to take the initiative for anything, they'd end up living themselves apart. They'd be living in close proximity, but with the back to the other, each one failing to communicate with the other.
Finding the compatible type for a NEET is like finding the correct person to be the first man on Mars. Very difficult, and tbh, it's not even clear what kind of person that should be.
Hence, most NEETs are loners.
