Boyfriend doesnt understand pregnancy

I feel so lost. This is our second baby, he knew what to expect - it was all planned.

I am 29+3weeks, my hormones are raging right now, I am tired, I am irritable, I am also still waking up 4-5 times per night with our 1 year old, im only getting between 3-4 hours sleep a night and she doesnt nap so I cant sleep in the day.

He works all day so I am looking after our daughter all day., as well as housework & i run my own online clothing business. Its hard.

Then he wants to come home and cuddle in bed, but he doesn’t want to just cuddle. He wants either sex or a handjob. I dont want to do that, I don’t want to do anything sexual, cuddling is the most I can handle right now and he doesnt understand.

He thinks I dont love him. So now I feel guilty that hes going to sleep feeling that way when its not true.

So then I sit up crying because im being selfish but I just cant help it I have no sexual feelings right now.

I dont know how to explain it to him or make him understand what I am going through.

He doesnt understand the pain im in, the way my hormones make me feel shit, the aches all over my body, the pressure of a baby moving around constantly, aswell as the tiredness from all the other things I do.
