hi, bird--as others have said, you seem to be doing extremely well in figuring out the line of crap he's trying to feed you. As another poster also said, he is showing you who he truly is, and you should surely believe him. He's looking for fun, fun, fun and no responsibility; as you mentioned, that is simply NOT the way a real, live, grown-up relationship works, whether HE wants to face that fact or not.
Don't know if you've considered or been to Alanon? It's a good place to get some real-world support as you move forward. I use SR and Alanon both, as each has its own strong points and I need all of those I can get!
Welcome to SR, and I hope you find strength and clarity in the days to come.
