Well you seem to be the rationale "adult" in the relationship and he's still acting like a teenager, especially regarding the "Crashing on your couch issue".
It seems like right now he wants to cake eat - have his free fun time but still be connected to you and that when you make arrangements to have your own life (i.e. setting up bank accounts) he gets huffy because he sees that as losing some control over you. I could be wrong but that's what it seems like to me.
It does seem positive that he wants to got MC with you, date you and spend additional time with you. That to me seems to be more than just going through the motions.
Are there any current dealbreaker issues for you going on right now, i.e. involvment with an OW?
