Boyfriend troubles

I’m 12 weeks pregnant and the father to my baby, my boyfriend is a sea clammer. Every time he comes home I somehow end up messing something up and he makes sure I know I did something wrong and makes me feel like shit every time. It’s like I’m not good enough and idk what to do anymore. I love him so much and he does treat me good but that’s when things are going his way. I’m at work today and he wanted me to go on the beach with him (I work at a snack shack in the summer) but my friend who also works here was helping me do something and he got upset that I was spending more time with her than him so he just left and said he’d see me around. What do I do?
