When you first fall in love with someone certain chemicals are released in your body that gives you the sensation of pleasure, joy and excitement. Later on these chemicals disappear and the feelings of love are felt through intimacy and closeness instead of butterflies in the stomach.
When a man meets another woman other than his wife and finds her attractive these chemicals are released once again whether he is a cheater or not. At this point cheaters go for the new relation while honest people avoid giving in to the feelings of attraction they felt.
People who don’t understand this concept might cheat
When this happens to a cheater he never realizes that the attraction he feels towards that person results from the hormones that are released in his body but instead he thinks that he loves that new person more than his spouse.
Cheaters might say something like:
I experience new feelings when i see her that i don’t experience with my wife anymore
I am more motivated to see him than to see my husband
I never seem to get bored of her
When we formulate these terms scientifically they become as follows:
I forget how those chemicals felt like, with that new person i can feel them again
More chemicals are pumped into my body when i see him than when i see my husband
i don’t think those chemicals will ever stop being released (the same thought that he first got when he married his wife)
