Why do some men fail to launch?

Dating a guy , older then me , doesn’t have his suit together and thought he would get it together- you know just sit back and watch the changes in his life and how he deals with things - I am unimpressed he stays in same routines money , perspective, health , wellbeing , wants , needs. I get a general feeling he believes the world owes him something - I feel like I don’t even want to attempt to assist him in changing his mindset as he “feels” too negative about the things that he believes are challenging and it shows. Lovely guys , very caring, generally great to be around but he appears to have no desire to make something more for himself or his children. It’s really demonstrated to me that living a life with someone like this is not for me. How do I communicate this in a break up situation?
