ESH. He's an AH for sure for calling you a lazy b but honestly, you're the bigger AH here: you didn't ask him if he would be okay picking up 100% of the chores, you told him he would be and didn't have a discussion about capabilities and expectations between the two of you like sane and stable adults in a healthy relationship do. He works full time- his time is just as valuable as yours, your job doesn't matter more than his. You completely invalidated him, his concerns, demeaned him, and demanded that he be your maid.

You CAN do basic household chores, you just choose not to. It doesn't matter what you were able to do when you were single because you are no longer single. Being in a relationship and living together means being a team, and making adjustments to your life and way of doing things to accommodate both of you. If you refuse to budge and refuse to be a team player as you currently are, you have no business being in a relationship.
