How to cope?

My husband left me today. I am 30 weeks pregnant so my emotions are so crazy. I don't know how to handle being in our house alone... I am so used to him being there it breaks me to be there without him & to know he isn't coming back. It's best for both of us but it's so hard. Will it get better?! I'm staying at my parents tonight bc I am afraid I will get too upset sleeping alone in our bed. Anyone else had to go thru this??
