Wanting to leave my partner

So a small back story, my partner cheated on me in the beginning of the year and I found out about all of it within a few days. He was going to bars almost every night or be out from 9pm at night and wouldn’t come home until 6AM got numbers and tried to sleep with people Then he started bringing a girl over to his friends house and they just sat in the car “talking I guess” Everything came out but after a couple of weeks I decided I wanted to work things out. He’s changed everything about not going out anymore leaving his phone with me whenever he’s home, he stopped smoking and makes his friends come over now. BUT there’s things that I’m still not happy with & these are things I’ve brought up several times throughout our 4 years relationship. We are in debt right now so I don’t make enough on my own and he barely makes anything his self but he still has enough afterwards for whatever we need. He’s the type of person where I’m always pushing him to be better, I’ve been looking to get a better job and building my business in the matter of a few months. but he gets mad when I try to tell him or even doubt him now about things he needs to get done based on what he tells me he wants to do but gets mad when I bring it up bc “he knows what he needs to do”. For example, he planned to get his CDL but got in a car crash (he’s okay) but he waited a whole month to find out if he could even still qualify to do it, was told he could by text msg and didn’t reply to that person for a whole week but replied with “expressing how relieved he is and that makes him want to study harder” and since then he hasn’t studied once. But has played his game and been drinking have his friends come over until 3 or 4 in the morning. Even before we got into debt, he told he’s going to get his GED. Told me that a year after we been together and open a real estate business. We’ve been together for 4 going on 5 years now and hasn’t made one single move. But I’ve literally given him information on ways how to go about it and we know to people who are in real estate and I’ve told him to talk to them but he refuses bc “he wants to do it on his own and talking to them isn’t much help” Anyways I guess that’s his personality but I’m not happy anymore, since I started my business, it’s made me open my eyes in many different ways and these past couple of weeks I just haven’t been feelings it anymore. I thought trying to fix our relationship after being cheated on is going to work but gosh there’s just something that still hasn’t changed and I’ve been up happy before the cheating happened and I think I’m starting to realize what I really want and idk I guess I feel bad that’s he’s been trying so hard to fix us and I’m just not wanting it anymore. He keeps telling how happy he is and how proud he’s changed the things he has for the better but idk every time I bring up the other things that hasn’t changed, hell say “ ill never be good enough for you” Am I wrong for wanting to leave now and not feeling happy anymore?
