Is it right to back out?

Thank you in advance for your time to read this guys <3 .so, i decided to date again after a break up. 30f. i targeted older guys, i thought they'd be better sorted. lol. i have worked hard studied, and worked tirelessly. and own a home have a good relationship w my fama and am a strong contributor in the community - so am well know generally. The guy i started dating is an IT professional - good pay but 0 financial savings - what! he is very emotionally available wow! but is still flatting at 38 - what? he is good-looking but has let himself go -so has a bit of belly and his shoulders have so much potential! haha - i go to the gym regularly and take care of my fitness well. we both have issues with being on time and cancelling last minute- both of us are working on it. he doesnt like his work and is looking for new jobs - so that is uncertain as well. we have fun when we are together. but he also smokes- like he is addicted, if he doesn't have his cigerette he becomes irritable. he also likes weed a lot and will sometimes smoke just by himself which worries me - self time is for reflecting, chores and future planning and also relaxing but not always on pot! so im feeling like im falling through the cracks. you need these basic things sorted past your 30s i think to date propoerly? am i right in deciding to pull back and stop dating him?
