You said you have pushed the subject of the woman at work because she is pretty.
It sounds like you absolutely wouldn't have had an issue with her if she was (in your eyes) ugly.
You called Lindsay Lohan a washed up crackhead. What a horrible thing to say.
Your attitude to women leaves a lot to be desired. You are reducing them to their looks and what you perceive to be their sexual 'value'.
You aren't just trying to control his behaviour, you're actually also trying to control his thoughts.
You have pushed and pushed and pushed him. The fact is, if porn is a dealbreaker for you when it comes to trust then you need to leave.
The bottom line is - you are obsessed with your partner finding other women attractive, whether porn, celebrities or a woman at work.
I actually understand why women find porn a dealbreaker even though it isn't one for me. But yours is rooted in wanting him to only find you attractive and you have reduced other women to their looks.
You say he has betrayed your trust. You have looked through his phone, his private phone. You are disgusted with what you've found but haven't spoken to him about this. Instead you are behaving in an increasingly controlling manner, thereby pushing him further away. If porn is a dealbreaker for you and he watches porn then you leave.
You can't say it's such a dealbreaker that you can't bear it and then stay in a relationship that is broken. Follow through on your beliefs if they are so strong.
This relationship is unhealthy. You are making it toxic.
I'm sorry but you have posted for advice and seem to be unable to take responsibility for your behaviour which incredibly controlling and paranoid.
