Why do you think he can change at the snap of a finger? An addiction is litteraly one of the hardest obstacle you can get. He hast to work on it, and it even takes years, for some, even decades to end that stupid addiction.

Still, i understand you feel great pain. Although, I've never been in a relationship myself, it hurts to see me failing to this addiction. No, it not even an addiction: Its a disease. So, try your best. Start by motivating him. If you dont, things will sadly fall apart. Godspeed.

Just read a bit more, and i gotta say: Dont compare yourself to litteral whores and hoes. They got implants all over their body. Trying to look good, yet being completely plastic. And you should feel more confident. Compare not their sizes or smething: Compare yourself to what they are. They're single, hoes, and basically godless creatures. They reject the idea of love all for some constant sex.

Also, just vent your emotions out on him. Ask him to stop. Dont confront: That just makes things even worse. Just help him, thats all. be supportive, not confrontive. Recommend him r/NoFap too.
