<human>: My boyfriend and I are thinking of co-habitating, we love each other very much but I have heard scary things about co-habitation. 

Such as: He won't ever marry because "why buy the cow when you can get the milk for free? (Horrible analogy) but I have been told co-habitation will result in the relationship never progressing. I'm afraid for us to make a decision that could hurt our relationship. Because I do want to in the *far future* get married. And I don't want our relationship to ever grow stagnant. 

We have been through a ton together, have greatly improved our communication and are on the same page. This is not some whirlwind romance (though often it feels like one) we have been through hard stuff and come out together. Which is the only reason I would want to, I only would want to with him. But the things I've heard make me afraid.

Provide a brief overview of the text.
