Worried my husband is turning into a misogynist

My husband has been displaying some weird behavioural patterns lately and I don't know what's going on with him. Some of them include:

-All of a sudden, he's smoking (mostly vaping, but I caught him with an actual cigarette the other day). He smoked when we first met, but stopped within four years of us being together. I knew he smoked very on and off, but now he's buying vape thingies monthly, sometimes twice a month. When I express my disappointment (and note, I didn't outright state that he must stop because I know it's his body and his right, but that doesn't mean I have to be happy about it), he gets SO angry at me and flies off the handle about why is he not allowed to do what he wants, he wishes he never got married so he could just do whatever he wants, etc.

- He's talking a LOT about how he never got with a lot of women before me. We were both each others firsts, and he claims he was so oblivious to women hitting in him before me, but yeah, really talks a lot about how he never had a wild phase. He has cheated on me twice (once right in the very beginning of our relationship, and then he had a full in affair (which we have moved on from), about five years ago.

- He watches a lot of videos, debate videos, that discuss men and women's issues and whenever the women are talking, he uses the "c" word a lot and basically thinks they're ridiculous. I've called him out on this more than once. Including this morning when I actually got really angry at him for it.

- He has stopped helping me around the house. Completely stopped, doesn't even do a dish anymore. I had a fight with him about this yesterday, because I realised the reason why I am so exhausted is because I am working a full time job and completely taking cae of the house, and he will come home and not even stick a load of laundry in the wash or anything. He did apologize and say he'll start helping more again, but I somehow doubt this will happen.

- He complains about everyone at work, but he *really* complains about two of the women at his work. At first I thought it was because he was attracted to them or had a crush on them, now I'm wondering if it's because he full on hates them (granted I know there's a guy he can't stand there either, but he doesn't talk about him nearly as much).

I actually sent him a message this morning saying it's like he's forgotten I'm a woman when he carries on, and I'm worried he's starting to hate women, which he hasn't responded to.

Does it sound like I have reason to worry? We've been together for 20 years and he's never been so hateful.
