I have some sympathy for those you mock. I was once there myself, though I would rarely let that be known when I was living it. But, I decided to change. While I have found contentment in backpacking solo for a week, I imagined what life could be like having one accepting person. With that as a goal, I worked on myself to enjoy the person I am, living independently, and joined activity groups. I started having a great time, and even with a failed, short, relationship, I didn't even know that I was creating a person that my future spouse desired.
The big thing here is you did the work and made a conscious effort. You invested in you and your own foundations. You set an example on how to suceed.
What has been so glaringly off putting about certain behaviours is that a relationship is seen as a status symbol and a remedy for one's personal struggles. And it's not.
There are several who have exhibited very similar behaviour patterns. Not once was the even theoretical female taken into consideration. It was always only expectations A - P. What could and will be gained on the currently abstract efforts of another.
There is no blank slate approach, instead unwritten criteria that needs to be met. (Yes, it can and does go both ways, but it lays ground work for fault finding.)
Like a writer too close to their own work, objectivity is moot. The chronic patterns and the tone of the context is a red flag.
It is a signal that maybe that individual is not emotionally capable of dealing with another's emotions and needs in a healthy way. Even in the most basic interactions the ratio of give and take is hugely uneven. These patterns repeat unless they are addressed.
It is the attitude that is bothersome that people are angry and resentful when others avoid them for being angry and resentful. You have to like yourself at least a little bit if others are to do the same.
And being okay with who we are and where one is at is a sign of emotional maturity and/or consciousness and personal foundation work. These are the people would did and understood the assignment.
We did the assignment. Might not have been a comfortable project, but the work got done. That is what it comes down to.
