Struggling.

I love my husband and he loves me. I'm writing this because I have no one else to tell. I am 33 weeks pregnant with our first child, a boy💙, my husband is full time working almost 10 hrs everyday. Today he came home and I could tell something was wrong but he won't talk to me instead he gets frustrated with me and starts to yell at me. I'm a mess and start to cry, all to say right now he's in the living watching tv and I'm in the room trying to pull myself together. I've asked him what was wrong and he said he was stressed out because we couldn't pay our rent this month. We have been having trouble with cash since i got pregnant bc ive been out of work due to extreme morning sickness and being anemic. All this to ask you, how do I help my husband? bc I don't know what to do.
