As per your story if true, your husband appears to be a modern-day Casanova.
While reporting him to the CID may or may not work, the matter is more than just taking away his job or putting him into jail over his relationships with other women in Qatar. His amorous nature will make him go for other women in your own city even while he stays with you.
As Shaki27 has stated, it is up to you now how you would like to handle this issue in your life as it is now more of a personal matter.
