How do you cope, when your husband leaves?

So my husband and I just had our last child in April. We have had a lot of ups and downs, more downs. Years of counseling. Well, this past weekend, we separated. I've reached out to him, few times and well he said he doesn't know what he wants. He doesn't want to give me false hopes, wants his family, but not the life we had. He doesn't want to be pressured, But, only time will tell. This is so hard. 
How have others coped with this? I've got million and one things running through my mind. Can others pls share your stories. Should I give him his space, and back off? He doesn't reach out at all! Could use the prayers, thanks! 😞😞
