Communication Breakdown

Me and my partner keep having communication break downs. We have moved two hours from our support network and he’s settled, bet a best mate and loves it. It’s a very small remote, but beautiful village. Me on the other hand has nobody but him. Moved in March and May I found out I’m pregnant (currently 15 weeks) and my partner is doing all practical bits like the renovation and providing as I’ve had the worst first trimester and now suffering with prenatal mental health issues struggling working a full time new job on top.
He’s constantly back on forth on withdrawing from cannabis. I said it’s been three years I can’t carry all of our moods right now. I’ve come back to my families and have had so much support and I really don’t want to go back.

He classes me struggling as moaning all the time, he says I’m a grown person to use my own initiative to renovate the house when I’ve struggled getting out of bed some days throwing up for ten weeks straight now mental health in gutter. Bear in mind I make sure food is in, he’s fed and the house is as clean as possible considering under Reno. He feels pressured to be at home more because I asked if he’d take me out for walks or chasing sunsets together instead of his spare time from work, Reno to have beers with his new mate. He deflects, avoids and creates arguments and it’s exhausting when he can see how poorly I am. I have no bond with my baby. I’m scared. I don’t want to go back there and be so isolated as he can’t give me what emotional support I need whilst going through this but I need to prepare for baby and it’s my first pregnancy, I have no idea.

I understand we are both overwhelmed and exhausted but I haven’t asked for anything but to feel safe emotionally whilst I’m so isolated and poorly which he can’t even do and just started getting arsey. Has anyone struggled or know how to reconnect? It’s been like this for years and I’m very emotional person since losing my mum years ago, I’ve done so much self work but pregnancy and the move has heightened everything and he knows but doesn’t acknowledge it.
