Irrational and hormonal?

I'm 5weeks pregnant. My husband is acting like nothing is happening. I keep asking him to read some books I got for him but he won't. I want to punch him in the face. I feel like I'm going through this alone. We both work, when I come home after working 10.5 hrs I do chores or grocery shopping, I try to plan dates. All he does is say he's tired and stressed from work. If this is how he's going to be I want a divorce. I just want to cry.  I'm so angry!!!! Am I being hormonal and irrational or do I have merit to feel how I do?
