In my own research, I found a frequent common element when working with men who are perpetual cheaters.
The first bond is chat between child and mother. It is a strong emotional love that continues until the child goes through their terrible two’s.
The terrible two’s is when a child first creates a separation with mother. In men who cheat, I frequently found that a younger sibling was born before the older child went through their terrible two’s.
When the mother’s attention switched to the newborn, the older child felt rejected in the mother’s love. This creates a fear of intimacy and an expectation of rejection that lasts throughout life, creating the cheating to ease the fear of intimacy.
Interesting theory!
