Hi Peter,
Well, all the best with your novel. Don't sit around counting rejection letters - do something positive with them. There are several papier-mache animals and robots hanging around my house, all made from rejection letters!!!!
House husband is no worse than housewife - (a title I deplore)! So don't despair. I think 'father' is just fine!!
Maybe you'd be brave enough to post a few chapters of your novel here at some point - between us all, we might be able to spot whatever it is that the publishers aren't liking!! But, like they say, no use sitting around - time to push on with the next one. Your comedy sounds like fun!
