How do I do this?

My husband just told me tonight that after 2 kids and 10 years together he wants a divorce.

We just moved across country and I have no one. No family, friends. He doesn’t want to try to work it out. He’s done. Sooo I’m sitting here wondering how on earth I will be able to live with only having the kids half the time. Until a month ago I’ve been a stay at home mom. My son is 6 and my daughter is 2.5. I’m so lost. What do I do? How do I cope with this?
