How come men can be so annoying

Mom of two girls here and baby boy on the way...Can anyone please tell me why men whine so much?!? I’m 31+weeks and tonight I’m having pains in my side. I was going to put the kids to bed since it’s my night and we have to stay in the room with our toddler for her to go to bed...but he went and did it. I saw he was having a hard time so I offered to help and he’s like “go away, I got it..you’re distracting.” He was saying this in a tone that I knew he was pissed and wanted me to do bedtime. So now what’s going to happen is he is going to bottle this incident up and bring it up in a few weeks upset 😒 when I told him I was in pain he said well I don’t feel good either. It’s always a battle of who is what and it’s annoying. I’m pregnanttttt! Do you not know what this does to the woman’s body. This bed time thing that’s been going on with our toddler for months has been putting so much stress on our relationship. We both work full time. I wake up with our toddler to get her ready and to daycare then go to work and he gets to sleep later and get older one to bus stop who does everything for herself. He acts like I don’t do anything sometimes. I want to scream. Sorry needed to vent somewhere.
