I really need advice.

Ive been with my SO for a year, we have had our ups and downs as every couple does. Im 17w2d pregnant, and sometimes i feel like id rather do this on my own. Sometimes im just so unhappy and feel like id rather him not be involved because he will make me upset where i cry in the shower and cry myself to sleep. He will cuss at me and make me feel stupid for feeling a certain way. Of course i want this family, i want things to get better and work out. But sometimes i really want to do it on my own so i can be less stressed and less upset. I love him, i really do. I just don’t know what to do, my hormones are a mess so that probably has an effect on all of this too.
