Sounds like he doesn't need or want you in particular. He just needs a wife and mother for his future kids, and your career is an obstacle to his plans. If the two of you stay together, one of you is going to need to sacrifice a lot. But each of you can achieve your own goals separately. It only makes sense to break up with him and pursue your goals. There is still time to find the right guy, who has goals that line up with yours and not against.
