He's putting a spin on the situation... instead of taking note of all the attention he is pouring into these other women... he turns the attention to you being jealous and insecure.
If all was well in the relationship... he would be inclined to tell you what he's doing... even share it with you to show you have nothing to worry about.
However he's not doing that... rather he's distracting you. Ever wondered why?
As those before me have said... dump him. You don't need the head games... and if he really loved you, he wouldn't be playing them to start with.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
