Hi, Melissa! Welcome; nice to meet you. Wow, we're having a twin boom here. You're our second HGer expecting twins this week! HG tends to get worse with each pregnancy, and with twins it's no wonder you're really struggling.
Your husband is typical, and that is so frustrating. I can remember so well the tantrums my husband would throw as he sorted through clean, wrinkly laundry. He just could not understand why I couldn't fold laundry if he set it on the bed next to me.
Him yelling, me crying and puking--happened many times throughout the courses of my HGs. It took him until my 4th time through to understand how HG worked, and I think it was because I actually felt well enough with that pregnancy to sit and interact with my family instead of dying in bed. He saw how much I struggled, how much every little effort cost me. Ladies in his office also learned of my HG and told him about their normal pregnancies, and he finally realized how far from normal HG is--I honestly don't believe he realized how unusual HG is compared to normal pregnancy. Plus, that last time he was forced by an angelic home health nurse to learn to run my fluids, and that seemed to be a real turning point for him.
I'm sure your husband is overwhelmed and frustrated, but I have no idea how to get men to understand that it's not about them! I think the best thing I did last time to ease the load (and therefor the frustration) for my husband was to line up housekeeping and meals for him. Attack the symptoms, maybe, and he'll relax? Is there any way you can have someone in to help out by running a couple loads of laundry or wiping down countertops? My grandma came a couple times per week and kept our house in decent order, and it eased tensions. Aside from that, perhaps getting him to read here or getting in touch with an HG volunteer from your area who can validate what you're going through and clue him in? Let me know if you'd like to find someone in your area.
I know others will have good ideas for you; I'll keep you in my thoughts as you work to get those little ones here. I'm sure the ladies in the 2nd Trimester folder would be thrilled to meet you, too. Best wishes!
