Honestly it sounds like you shouldn’t be together. Not to be that redditor that’s like “ break up immediately” but it seems like what both of y’all want don’t align. He’s probably embarrassed that you out earn him which could be why he lied about his salary. From what I’ve read it sounds like you want someone who’s career oriented or a high earner, you should look for someone like that. He doesn’t seems to be that and there’s no use to try to coach him into it.
