will "find someone else."   Eighty percent of the women are seeking twenty percent of the men.  Women seem to seriously overrate themselves, or else don't consider any of their own attributes except looks, so they reject men that they should accept.  At the same time, many men are bad at evaluating all of the positives they can bring to the table, so they are often not as confident as they should be in approaching women that may be more attractive than they are.  Looks are only one aspect, and both sexes sometimes fail to consider much else when looking for a partner.  

You can have a thriving sex industry and yet you can have people committing these crimes because their value system is  not in congruence with the moral code that we as a society have adopted, and have passed laws based on the same code.  For e.g. In some countries infidelity is a crime punishable by capital punishment. In America  it isn't.  

 
People commit the crimes because they feel rejected and insulted. They can't overcome the rejection and they get desperate.  What really needs to happen is people need to practice patience, restrain, detachment, mindfulness, empathy.   They need to understand actions have consequences and think twice before doing anything that is irreversible.  

 
And none of these qualities have anything  to do with sex or sex industry.
