The connection is far gone.

I recently gave birth, and we also have a 19 month old. My husband works 6 days a week long hours we sleep in different rooms. One parent to each child.... My husband refuses to let our kids sleep on their own he will sleep in our toddlers room and I'll have the newborn. He wakes up in the morning with 1-2 hours before he has to start work, he goes to work, when he comes home we are asleep. My marriage has pretty much gone completely down hill. There's no emotion left in me... No connection! Nothing! His literally just become this guy that lives with me.. Sex is non existent as I'm not on any BC yet and it's hard to have sex with someone who isn't here. I know he works long shifts and I praise him for that but I feel so empty there's no spark and I think the lack of affection and intimacy from me is making him either depressed or angry I'm unsure of which one. At the start I was depressed but I then became numb now I don't really feel anything I actually feel as if I'm falling out of love with my husband.
