He goes out every night almost and leaves us home. I'm trying to stay positive but it's hard

I know the feeling 😢

Keep strong honey. I went thru this with my last child. It was hard but I left my ex's home. That's the only way I was able to grow. I went to a shelter and worked my way up. I had a little postpartum but I overcame it. You can too. Just start off my making a realistic plan to move to your own place with your beautiful baby. It won't be easy but your strong and you can do it!
