My conclusion is this man is narcissistic. Sorry but his jibber jabber is giving me a headache and all his intellectual fluff and big words are just pissing me off. The relationship has been shit for 5years-trying an open relationship wont fix it, neither will getting married, buying a house, having kids etc.. you could try until your blue in the face to make this mess of a relationship work but its dysfunctional-always has been..
And I still think you have issues with equality. Your happy to be open but you wont be when she does the same. Your gonna destroy each other
