I'm so sorry to hear this OP. Here is my hand to hold and a hug as well (I'm American so I can help being annoyingly demonstrative 
I can't relate to the divorcing part, but I can relate to breaking up with what I thought was the love of my life and losing my best friend. It was nearly 20 years ago, and I remember it as exactly as you describe it-wanting to talk to him about it and have him comfort and cuddle you because he is your best friend and you built your life around him. Forgive me if I'm wrong about the last part, but that's the vibe I get from you post and it reminds me of my first love.
There is good news on the horizon though. And, that is, that even though the loss feels great and the challenge insurmountable , it isn't. You will get through this This too, shall pass I know it doesn't feel that way right now, you just feel like you've been left adrift, alone in a giant sea, with no end in sight...it's there though, I promise. You will find your strength to swim to shore and you will create a new life in beautiful, albeit foreign land.
The main thing you have to focus on is your child and all the practicalities mentioned above. Please make sure to lean on friends and family (when the time is right) also, if you it is feasible, I would recommend going to see a therapist by yourself to help you get through this difficult time. Eat a whole pint of Ben n Jerry's (or the equivalent), have a good cry, and watch some movies or Skybox to take your mind off things. Go for a walk if you can, even if it's with your baby in a sling and it's the end of the road. Don't forget to take a shower, brush your teeth and comb your hair. Put on make up today (even if it's just lipstick and a little blush) This is your warrior paint. It will giver you power to face the days ahead.
I know that some of my suggestions sound simple or even a little silly, but they have worked for me and friends of mine going through the same thing. Best of luck and I wish you nothing but courage and strength. You are stronger than you know
For you,
