Hi honey may i ask you to let go of him your getting nowhere with him , you should not beg for anything let go with love then start looking after no1 that's you , Please take care
It sounds like he'd rather be alone with his hand and his porn than to have a real girlfriend. He is clearly obsessed with this, I mean doing it at work and every free moment he has? This is clearly addict behavior.
I really think you need to break up with him and find a normal boyfriend who isn't an addict. This so called relationship is kind of a joke since he's so much more interested in his "fix" than he is in his living breathing girlfriend.
The whole issue is, and you live with it - it is unlikely his behaviour will ever change, so if it makes you uncomfortable, then don't waste anymore of your time on the guy
He needs professional help and see a therapist specialised in porn addiction. Porn is like a drug to the brain, its a wider spread issue then most people realise. Straight men watch transgender porn as normal porn doesnt do it for them anymore. They need more extreme material to get off. Watching rape is quite worrying as that shows his brain is already numbed down a lot. It can go awfully wrong from here. Please rest assured this behaviour has nothing to do with you personally. But if he doesnt get help it will only get worse. Google porn addiction and find out more for yourself. Good luck!
