Unfortunately, most of us beat around the truth and aren't upfront and honest about things. It would be nice and more convenient if we all were, but if we weren't so insecure and unsure of ourselves, we would be.
The bottom line is that he is keeping you around for all the intimacy parts, but when he is away from you, you better believe he isn't going to be thinking of you. I miss the intimacy of my past relationships, and it's kept me wanting that with somebody else that I didn't feel the same way about. I miss that part, but it doesn't really matter with who. He may find that with somebody else and then he won't need it with you.
The fact that he is confused about what he wants means he wants the best of both worlds: cuddle time with you, keeping the options open for somebody else. I've been a guy that has done it, and as sick as it sounds, I've kept a girl around for years off and on but not really specifying a title and keeping my options open. It didn't end good for her or for me.
Try the honesty route, but if you get the misdirection, I would cut your ties. It may hurt, it may be scary, but you have to recognize that you are what's important here and what you want, not what he wants. If what you want doesn't agree with him, there is no convincing you can do by waiting around.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
