Leave baby daddy ???

Hi all, I want some advice or guidance or anyone else who can possibly relate to my situation. I feel very alone as of late because I always end up feeling my baby daddy makes me feel incompetent or a bad mother. Let me give some backstory to my drama with my son’s father. When I first gave birth to our son, EVERYONE was in town for his brother’s wedding. I clearly communicated I did NOT want anyone visiting us at this time because I knew distant relatives would be in town. Day after their wedding comes and you guessed it, 12 distant relatives showed up at our front door wanting to see the baby. HELL NO! I’m in no condition to have visitors or see people, why isn’t FaceTime adequate especially if we need privacy. I completely blame my baby daddy for this because he is such a mama’s boy himself that he couldn’t tell his mom no. Some time goes by, I also had trouble with breast feeding and same situation happens again where my baby daddy got frustrated and called his mom to “help” us with feeding. I didn’t want this as I knew the bottle would ruin any progress I’ve made with latching and producing and of course he calls her at 2am to come to the house and she gives the baby a bottle. Mind you, this whole time our son was still at a healthy weight and the doctor gave the ok to continue trying to breastfeed. Ever since these 2 incidents I’ve always found that anything my baby daddy says hurts me and makes me feel inadequate and I hate he always involves his mom. This brings me to yesterday, where brought my son to Disneyland. When we got back home my son was cold because he spilled water on himself and he was shivering because I wanted to rush home after the park to get him to bed. He was appropriately dressed and we live 50 minutes from the park. My baby daddy sees him shivering and he freaked out and yelled at me “why do you have to take him places? You don’t have to bring him!” Of course this made me very upset, and made me feel like a bad mom. I guess all in all what I’m trying to ask this community is, does anyone else relate to a partner that makes them feel incompetent or a bad parent? Also, what would you do or how would you react to your partners yelling at you for something like this? I feel so alone and unsupported and at the same time all this history of when we first had our son makes me want to break off our relationship and try to coparent. I feel so done with my baby daddy, we aren’t married yet so would separating be the best option? Thank you for anyone who’s read this entire message and any input I would be so grateful for.
