Bf acting some type of way

My boyfriend of 8 years and I are expecting our 2nd baby. I'm getting induced in 2 w and the past couple weeks hes been acting shitty. Just coming home in a shitty mood, nasty look on his face, nit picks at everything, and wants to argue over shit that doesnt even matter to him. Honestly I'm over it. Our child is due in a few weeks and the distance between us couldn't be any further. Really not sure what to do. I honestly just want to cry. If he's going to act like this, I wish he didnt have to come with me when I get induced.

Were good financially and nothing major has changed except that I got my induction date. Which btw, having another was entirely 100% his idea and he quite literally took it into his own hands to do it. He wanted this.

If it's not the baby, it's obviously a problem with me. Idk if anyone remembers, but I made a post about getting a haircut and he told me he hated it and he felt like he wakes up next to a boy.

I know the obvious response is to talk to him but I'm 9 months pregnant, and I just dont want to deal with it at the moment. Just want to be at peace before labor. But I know that's not the right thing to do and it obviously needs talked about.
