&gt;I want a romantic partner who will want to cohabit with me at some stage of the future, and if that works out, we can buy a house together down the line and own pets, and love and support each other through our lives. 

OK. But what of the cost of living in having that life? Your career choices? Your partner's career choices and how they match up with yours? Who sacrifices what when it comes to each other's career? Who's the sole breadwinner? Where do you want to live? What's the "progression" of narrative going to be like when you're joint to the hip with a significant other? 

&gt; Unfortunately I can't get him to even consider the idea of moving out with me, so we have been stagnating. 

That's fair. He either doesn't know what he wants at all, or he knows what he wants and it's different to yours, but he doesn't want to lose the benefits he has from being in a relationship with you. 

His words sound clever but to me they're just a bunch of fluffed up meaningless bullshit that you wouldn't find surprising in a C grade college paper. You can't have any relationship with someone who is the living embodiment of the phrase "I don't know".
