The Lost Letters of William Woolf discussion

Some reviewers have expressed disappointment at the ending. I don't agree with that although I found it rather cliched. I also thought that the epilogue could suggest that the author believes that a woman and/or a relationship can only truly find fulfillment in parenthood. What do you think?

1) What was the author's intent behind having Claire give up her job, where she was thriving and about to make partner, in favour of making William the breadwinner? Is this the suggestion that practicality should always come second to passion? And/or a deference to the societal patriarchal expectation that the man should be the breadwinner less his ego be crushed like William's was at the beginning?
2) Are all their problems supposed to be solved now that they have a baby? Does this tie into a larger notion that a woman's wants can be placated by having a small body to take care of? There is no mention in the end as to how the couple resolved their differences.

I'm not convinced there is a moral to be taken from this. In the end, The Lost Letters of William Woolf was a gripping tale of two people who had to work through some problems that are very common but very real to a young couple's journey together. However it ends depends on the circumstances of the situation, further minute details we may not be privy to, and the desires of all those involved.
