This is a question that usually resolves itself.

If your SO went into a relationship with someone who he/she knew was extremely passionate about building things, and they somehow expected this to "change", they are delusional, dishonest, or both.

Did you really want to spend the rest of your life with a delusional, dishonest, controlling individual anyway?

Yeah, didn't think so. In this event, you move on and find someone who doesn't try to hamstring your dreams and crush your soul. They do exist, and your life will be richer for it.
