He saw my msg venting about him to a friend on my phone

So I haven't slept since I was 5 months pregnant and my baby is now 6 mo. He is the breadwinner and my pregnancy was very complicated and expensive. He's a broker with no salary and during my pregnancy not one deal was closed so there was lots of borrowing and stressful time which is still going on. So he's mentally under a load of stress. Then there was my mum and his dad's hospitalisation and those bills which are crazy sky-high! Over a 200k $ are the bills and borrowed and everything ... So that's him and I'm jobless, can't afford and don't trust day care. First time mum and figuring things on my own with absolutely no help so I'm awake 22hrs from the 24 and the 2 hrs of sleep is all stressful as I'm constantly worried about the baby. So I was ranting about being tired and haven't had a proper sleep for months and that the night before I fainted right by the bed but my husband didn't noticed because his head was into his phone. I laid down on a cold floor for an hour and woke up with a massive muscle and joints pain I got up tripped a few more times while dragging myself towards the fridge to take some dates for my blood pressure and came back to bed and his head is still in the freaking phone. I even got upset and asked him if he even noticed me almost dying right in front of his face and he said no and continued with watching something meaningless on his phone. He saw the msg and asked me who the person is and I got upset and asked why are you going through my msgs? And he didn't continue the conversation and left the house and got back when we were both asleep. Then went out early morning and left his wedding ring behind on the table. So here I am trying to figure either fix things or let him carry on with the childish behaviour
