Husband watches porn because of me

I caught him yesterday watching porn. I was upset. I confronted him and he says it is because of me, I don’t staisfy his needs and I suck at everything and he said “tell me one thing that you do for me?” I’m like you tell me what you do for me, zero appreciation and he thinks the mom job is easy peasy, he sleeps peacefully at night while I wake up to feed, and never once have I complained.. I have a 4 year old daughter and just had a baby who is 2.5 months. I’m just very busy and my hands are full managing two kiddos; it sucks my energy. I haven’t left the house since Saturday. I dunno what I did wrong.. just cause he didn’t get his sex (he attempted to a week ago but I’m not ready and told him that. He got mad and said the sofa is better than me lol wtf.)

Am I wrong here?
