Can someone please tell me that I'm a bad wife so I can quit beating myself up over how crappy my marriage is and start fixing it?

The way I do everything is the wrong day to do it or he can do it better. I think of things to do for him that would be considerate. For example, mowed the incredibly large backyard today so he wouldn't have to do it. His response? "Well thanks, but I wanted to do it." We work the same amount of hours (most of the year...I'm a teacher), but God forbid he does 50% of the chores. He does what he wants to do and whatever he doesn't like doing, I have to do it. I feel like it's always about him, this "poor me" attitude that he puts off.

Whenever I cook a meal, it almost always ends up with, "Well, you know what I would have done?"

Makes sure he lets everyone know what idiotic thing(s) I've done lately to make himself look superior. He loves doing this in front of my family.

Doesn't show affection to me at all except for the once-a-month (maybe) roll in the hay when he has to get it out of his system.

I'm feeling very unloved and felt this way for awhile. We talk about it every few months when I finally can't handle it anymore and nothing gets resolved. I wish I could tell myself that it's all my fault and I'm the terrible one, but I just don't feel it in my heart that it's the truth. Don't know what I can do to fix it. Any advice would be greatly appreciated.
