Military Family Issues

Hey everyone, I just wanted some advice and coping mechanisms for what I’m going through. My husband and I were dual military in the navy, he recently got out. I am still in. He suffers majorly from depression, and we have a beautiful 8 month old baby together. About a month ago, he went to Oregon back to his family with my baby, and then I took leave a week later to see them and we all came back to VA together. Mostly because we needed a break from each other and our marriage was failing, it was a nice break to focus on myself due to Post partum depression. I feel a lot better now, but our relationship is rocky. We have good days, and bad. I told him that I’m not going to stand for the arguing and anger infront of the baby, or at all anymore. I do believe it will if it already hasn’t, effected my child. So he has decided to reach out and get help in Oregon. He is taking the baby with him until i transfer to the west coast in 5 months to live on a ship and drive four hours when I can to see them to save money for our future to buy a house/pay debt off. I have to lose A LOT of weight and make sure I’m mentally okay to go back to sea, but knowing my family is leaving next week, it’s making me more sad. What do I do? What can I do? I love them both so much, I know his family will take amazing care of my baby and my husband will get the care he needs, but I feel like a failure. I don’t want to seem like I’m just giving my baby up. I love them both so much. Any advice?
