I can see both sides. I see that it is not fair to you that he is leaving the burden of everything home family related. He is not being as reponsible as you. BUT, this is temporary right? Once he finishes, he can begin to take over the reponsibility I would imagine. Has he said anything like that to you? Getting a PhD is not easy and he should be encouraged and not burdened on that path. It demands respect and patience. If you knew he wanted to get a PhD, why wouldn’t you realize it was a sarafice for a given time? And adding a baby to the mix is poorly timed and irresponsible on both of your parts. Also, it seems you may have post-partum depression. See a doctor asap! Your husband cannot help you with that!
