I've never seen something so true. My ex's are all explained right here
astro observation about men with moon in 3rd house:
I have observed that men with moon in 3rd house have mommy issues. Regardless of the signs it is placed in, but especially in the air signs. These men tend to talk very highly of their mother but tend to overlook the emotional neglect, dismissal and sabotage that their mothers placed in them. These men grow up with low self esteem and seek to find a woman who can fill the void that their mother left. Their mother could be a devouring mom who made them feel emasculate by smothering and controlling them a lot.
Unfortunately, many of them do not reach this self awareness and do not heal their mother complex. Their mother could be outwardly loving but inwardly had a complex relationship with them. Their mother also tend to have a lot of expectations from their son and the son feels guilty and weak later in life when trying to do self love.
Of course how this energy manifests depends on the rest of the chart. A man might attach himself to a mother like figure to appease her. Or a man might become a player and play with hearts of many women to satiate his misogyny.
These men also tend to be on their phones a lot. They're either talking on call or chatting with someone almost all the time.
They can show an unhealthy dependence on their mother, and later on any woman who resembles their mother. In one case, a man was dependent on his sister to guide him through life and in another case the man was dependent on his girlfriend to take decisions for his life. This is case of Puer Aeternus. These men can show lack of decision making power despite having talent and skills. They also tend to have a restricted insecure relationship with their partner because the partner is a rival to their mother. The man constantly seeks his mother in all women or dismisses them as worthless. So, this man only values women who remind them of their mother.
The other is the case of Don Juanism where the man seeks a perfection image of a woman in every woman. This perfection is the image of his mother. He shows great difficulty in emotional intimacy because he has this image of a perfect mother in his mind. He only wants that. Since he never finds that perfection he is eternally dissatisfied with who he has in life.
