My husband wants to change his career paths but I don't think it's a good idea because we have kids and our home to take care of. He's really unhappy with his job but I think he should be more responsible. Should I prioritize his happiness and support him or tell him to do the responsible thing?

I've been through the same thing. We've argued about it for how many months. I was also pregnant with our second child that time but he didn't even bother. The only thing important to him that time was to quit his job because he's unhappy anymore. I wasn't able to control him. He left his job even before I gave birth so obviously I shouldered all the expenses for the succeeding months. If he has a clear career path that he wants to take, maybe it's fine. But if none, better convince him to have a concrete plan first before leaving his current job.
