Am I making excuses for him?

It’s a lot but here I go... idk if I need to vent or I need advise. To start we are both in our 30’s . I am more financial stable and different stage in life than him. I have a career and looking at figuring out next stage. He had past drug issues and family issues from his past so it put him behind me when comes to a career and being stable . We have been only dating for 1 year and it be 2 in may. I did not know him during his dark times but I can see how it effected him. Since being together he has lied a lot and I have caught him in lies and confronted him about it. Living together he didn’t have a sense of taking care of a home which is because I think of his past. The biggest Thing in our relationship is that he cheated . Where I caught him with another girl in our apartment on the couch watching a movie. We were in a middle of arguing about something I went to stay at my moms and he texted me asking me when i was coming home and I said the next day but came back that day and caught him cuddled with a girl. Some girl he just met online no sex just watching movie in the dark. We argued and eventually I took him back again making excuses for why he did it. Now he’s been a lot better I think finally appreciates me and see that I have been stable thing in his life. I check his phone time to time and no creeping .He doesn’t know I look but I don’t trust him and I know a big part of a relationship is trust . I am slowly building it but then part of me is tired. We are doing better but another thing is his work. When we met he wasnt financial doing good and I helped him a lot and I didn’t mind it because he at least worked. But during COVID he quit and job because he was unhappy instead of being thankful he has a job during these awful times. He started to drive for Uber and I had to pick up the slack with bills and now he found a job and he complains so much about it and not be thankful about what he has. He wishes he was at his old job ( the one he quit because he was unhappy) . And it stresses me out that he’s so negative and just be thankful and work and if he’s so unhappy with these jobs why he doesn’t try better himself . Our lease is up in august and I’m torn about living with him again. I think we moved in too fast and I know he’s getting better or am I making excuses for him ? I am at point in my life I want start talking about marriage and children . It isn’t even on his radar now because where he is in life. He does want all that but he says when he gets a better job. But how can he get a better job if he doesn’t know what he want to do? He’s being so much better and so sweet and he try’s but idk if it is too late. Please any advise will be great.
