When things get mundane. I really need advice(lengthy post)

Last night, my fiance and I got into our first argument while me being pregnant. And it was rough and this argument lasted 3 hours. Over various things...mainly me being the worst significant other ever. Ive been with him for 8 years. I fight my own personal daily battles of depression..and i have never been a good talker ever in my life. I give him major props for sticking with me for 8 years with me having the worst communication skills 😢 for example I NEVER go to him for anything..i have always felt like if I am asking someone for help..with advice, money, how to handle soemthing that I failed. When I was really young after my parents got a divorce we had NOTHING...my mom left us girls home with no electric, no water, no utilities...there were times I would have to go to the neighbors and ask for a gallon of water..or basic necessities. As a child I had to swallow any pride ive ever had. So as an adult id rather drown then ask for help. You can see how this would be an issue in a relationship. As men like to feel they are helping in any way. I have went 8 years not asking a single thing from my sweet fiance. And I would rather struggle than ask for help at all. With money or anything...this is causing MAJOR issues. Heres my other issue. I work Monday Through Friday 8-5. My life is pretty repetitive...and he works 3 to 4 days. Our daily " surface " conversations are ruining us. Is this liek thsi with anyone else? The " hows your day going" " hope its going well" " cant wait to get home" BS is really a downer. But not texting him all day? That sounds rough too. How do i get over thesse surface conversations. We argued about that as well. Cause im just a "fake" surface talker.

Im in desperate need of advice

Thanks Ladies
