Divorce...8 months pregnant

.....my husband just told me that he wants a divorce at the end of December. I literally have 1 month until I'm due. He wants a divorce because he feels that he can't handle the stress of having a wife and child to take care of when he starts medical school next year. That he doesn't think he can be the father our son deserves and the husband I deserve. I don't know what to do. I'm so upset. I dont even know how to feel or react. We've been together since freshman year of high school and have even been married for over 2 years before falling pregnant. We both understood the stresses of what would come. He was crying saying he still loved me and still thought I was his best friend and still wanted to be in both of our lives. That he loves our unborn child more than anything. But that he won't be able to become a doctor with "the constant weight of the entire world" on his shoulders. I'm so broken...my little family meant so much to me and now it's gone in the blink of an eye. I'm not angry with him...because having been with him since we were in high school together I know the internal struggles that he faces and how hard some things are for him. I am his only family. I'm just so beyond sad that I'm losing the love of my life and that there's nothing I can do about it. I've never felt so alone. Baby is due Novemeber 9th. 💔 I hope this new stress and depression doesn't hurt my little one.
