I can't stop argueing with my partner😭

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
Ever since my son was born all me and my partner have done is argue, i have said such horrible things. It's mainly me causing all the arguements, but he angers me so much. i seriously don't know what's wrong with me! I feel i don't want to be in a relationship with him anymore. What should i do ladies? I honestly can't take this argueing anymore.
