"Oscar Frances and the Eternal Sadness"

Main character Henry is tired of his mundane life with his wife, Kim. Kim is portrayed as some what lazy (preparing freezer burned food in the microwave and canned fruit). Kim won't even water the peppers she is adamant to have planted every year.Henry even pees on the seat to the toilet to get some kind of reaction out of Kim but he never does. Henry spends the story reminiscing about his past love, Zoe and is regretting letting her go. Henry goes to the attic finally decides to read a book Zoe gave him a long time ago on to find a marriage proposal on the inside. The main reason Henry broke up with Zoe in the first place is because he was tired of their long distance relationship only to find out Zoe was willing to move for him. At the end, Henry gets out and old bag of pot and fires up a blunt.

I liked the descriptions used in the story: How the simple task of watering peppers is used to show how lazy his wife is which also fuels his dislike for bell peppers. I also like how he said the peppers they planted lacked the pep described in their name.
*I would like to know more about Henry's past relationship with Kim and well as Zoe. When and why did his relationship with Zoe become long distant.
*Some Parts I was unsure about:
1.During Henry's dream where it say the first step was lined with blood, did you mean "relatives". I ask that because the next sentence says his mother and sisters are there.
2. I failed to see what about this dream gave him an erection, especially with his mother and sister present. I would think him falling down the steps would instantly kill a boner.
3. What does "Baby beagle boy come see me in the spring" mean? I see that this may be referring to the beagle's character getting his ear nibbled on by the owl in the drawing in the book. This part may need to be redone to come across more clearly.
4. Also, I was unable to connect the relevance of the sentence on page 1 about Tyler to the rest of the story as well as the statement about the bathroom being refinished and the description of the bathroom itself.
