Is this all Eve's fault?

Why is it that the expectation to take care of the children falls on the woman? It does at least in my house. I ask my husband why, but he can't seem to answer me. I don't understand-- I work a FULL TIME job. So, why is it that I am also mainly responsible for caring for our son? It's funny because before we got married, we talked a lot about what our life would be like. My husband and I both agreed that we would both work and we would both share the responsibilities of our home, and when we had children, we would co-parent. My husband was clear about the fact that he didn't believe in traditional male/female roles. I thought that I was entering a partnership. Six years later, this is definitely not a partnership.

It's an unspoken expectation that ultimately, I am responsible for caring for our child. I try to talk to my husband about it, but he ignores my requests to talk about this or he denies that this is the case. It sucks.

Tonight, I call my husband and tell him that he needs to come home on time because he has to give our son a bath. You know what he tells me? He says that he is tired and can't do it tonight. TIRED! Like I am not thoroughly exhausted myself. Honestly, how does he even think that he can tell me that he is too tired to give our child a bath. Why is that acceptable? Can I say that I am too tired to breastfeed our son? Can I say that I am too tired to change his diaper? NO. Because as a parent, one has to put the needs of his/her child ahead of one's own. Right? You're probably wondering who ended up giving the babe a bath. Or maybe you don't need to ask because, of course, I was the one who gave the baby a bath.
So, my question is, why are expectations different for men and women? Does anyone else have this issue in their home? How do you tackle it? I would love to hear how other people deal with this kind of situation. Please leave a comment.
