Your guy is all yours - and happily so. He loves being around you, and he totally sees you as a couple. It looks like you two have a great future together - if you want it!
It sounds like you and your guy are a fairly new couple. He's into you, but he's not willing to bet his life on it. But if you've been together for a while, you may need to consider why he's not crazy for you yet!
Even though you may have feelings to this guy, he has no ties to you. You'll never get more than a casual fling from him - even if he tells you otherwise. His thoughtless actions speak louder than his sweet words!
