I resent my husband since having our baby

I'm starting to resent my husband since having our baby in September. I feel like he gets to have a lot of alone time and go out with friends while I'm stuck at home with our son. It's like his life hasn't changed one bit post baby. Everything he does gets on my nerves. He used to help with chores around the house but expects me to do it all now that I'm home plus look after the baby. He acts very differently around me as well. If I express a concern or how I'm feeling he'd roll his eyes at me as if I'm stupid. I'm not very happy in our relationship and have even considered leaving him. A lot of issues that seemed small before we had a baby just seem so much worse now. Has anyone else felt like this?
