The receipt for the perfect partner seems easy..
1. good charming looks (can’t really do much about this expect do dress-up/makeup and sports avoid crystal meth)
2. success in the satanistic economy (psychopaths are very successful here)
Need scientific proof: look here https://altcoopsys.org/2018/10/23/upper-level-management-and-ceos-more-evil-than-the-average-citizen/
3. loving caring kind personality, developed human being, social skills, opposite of a psychopath
3.1. not too much traumatized childhood, mental illness, hopefully parents were no narcissistic psychopaths
4. same degree of intelligence as you have
5. similar taste/hobbies
… “easy?” isn’t it.
You ask for the almost impossible – a loving caring psychopath.
By nature psychopaths lack empathy and therefore will be ignorant arrogant selfish and very manipulative.
You give them love – you get money and nothing but money in return.
In the end – psychopaths may be successful in business but fail in marriage.
In the end they also feel lonely – forsaken – have only temporary relationships – everybody hates them.
A tragedy for the whole society / family.
No way out?
