Problems w/my husband & not sure what to do…

I’m currently 28 weeks pregnant with my 3rd child. My husband and I have been together for almost 6 years… I have a 15 year old son, and we share a 1 year old daughter. I had an emergency c-section with my daughter last January… and then I developed postpartum preeclampsia. A month after my c-section, I caught the flu. It was really bad… it turned into double pneumonia and I went septic! Scary times. My husband was also very sick with the flu at home, and so was our 1 month old baby. I was hospitalized for a week and then came home… but it was too soon. A day later, I ended up hospitalized again for another week. Had to have a chest tube placed for a few days to drain my lung. 😣 My husband didn’t come up to visit me at all in those 2 weeks… (to be fair, I told him not to come up. He was super sick at home and also taking care of our sick newborn!) So I try not to let that get to me… but when my son asked my husband if I was going to be okay while I was hospitalized, he said “She’s on vacation in there”. It’s like he was pissed that I was admitted and he had to take care of our infant all on his own while being sick. I tried letting this stuff go… we are expecting our 2nd baby together in late April, and I’m wanting this marriage to work. We just found out last week that our baby boy (in the womb) has a heart defect. He will most likely have to have open heart surgery right after he’s born. I’m having a very hard time handling this… I’m very pregnant, I have PTSD from everything that happened after my c-section last year, and I’m just plain scared about what the future holds for my baby boy. I’ve been thinking a lot about things lately, and I’ve just been super depressed. Today was a pretty normal Saturday for us: my daughter woke us up at 7 AM, I changed her diaper and clothes, fed her breakfast and let her play for a few. All while my husband sleeps. He does this EVERY weekend. He used to wake up around 11ish and let me take a nap for an hour… because I’m pregnant and exhausted! But now I just have to take a nap when my daughter does… which she never wants to nap anymore. My husband will wake up around 11 AM or noon and watch videos on his phone for a couple hours. THEN he will finally come into the living room and play with our daughter for a minute. I take her into the bedroom a couple times while he’s playing on his phone in the morning/afternoon, but he doesn’t get up. After he’s up for the day, he asks me if I made breakfast and when I said no, he sighs and says “Okay, I’ll take care of it”. He’s constantly annoyed with me because I’m not doing enough, I guess. I just wish he would help me out more… I feel like it’s all on me. He’s 16 years older than me (I’m 35 and he’s 51) so I try to cut him some slack. But damn… I’m tired! We both work at a truck factory. When I call off from work he will get pissed and talk about how bad off our money situation is. I just feel like this isn’t working out. Am I just being hormonal?
