Am I wrong for wanting to leave?

My boyfriend and I have been together for almost 7 years. He’s cheated multiple times and I keep letting him come back. The last time he came back three years ago he quit drinking and he hasn’t cheated since. Is it wrong for me to want to leave now that he’s actually trying? I love him but I keep thinking and dreaming about him cheating on me and I’ve honestly just been unhappy. Aside from the cheating hes gotten lazy. Doesn’t work unless I need his help on my jobs. Has multiple people living in our house but I’m the only one cooking, cleaning and stressing about bills.
