what do I do?

My husband and I have a 2 month old baby girl, I go back to work starting next week and my mom has graciously offered to babysit for free on the days we need someone. All the sudden my husband decides he doesn't like my family, doesn't trust them, and then tells me that I need to choose between him and them. And basically drop my family all together. I am heartbroken. My family means so much to me... he has had a series of depression and anxiety over the last couple of years and I am sure this is bringing it on. What do I do? I shouldn't have to choose between either...
