Need to get it out.

My partner has been away a week, taking a job in the mines. He's on a three week on, one week off roster. This weekend we moved into our own house, me leaving my roommates and him his brother. As he wasn't here, a lot of the burden fell on me to move us. I'm over 18 weeks pregnant.
As I sit around today, exhausted from yesterday's efforts, in a much bigger space than I am used to, I can't help but feel alone. I feel like I'm in this alone. Here for this baby alone. I feel like a soon-to-be single mother and it's really getting me down. I never wanted to be a single mother, im still getting used to the idea of being pregnant. I just want to cry.
I know I should talk to him about this, but he doesn't really want to be there himself- his reasons are solely for our developing family. If I told him, I know he'd be on the next flight home. It would be so selfish of me to do that.
I just needed to get that out.
