As Paul's wife I thought I might respond.
It was not so much the fact that he was concerned about money etc. That is fine and I was as well. The issue really was that from my perspective I did not see someone who was happy we were pregnant. Even when I told him his response was not that of a joyed husband finding out he was to be a father, even though we were actually trying.
He was banking on the fact that it would take about 12 months which is what we expected given my having PCOS and such. There was not one moment where I thought he was at all happy about my being pregnant, just worried about the money.
Even his mother said when she found out "But what about all your plans!!!" and when I miscarried I got "it was probably for the best".
What he was saying really when he wrote that is that there was no balance. You can still be mindful of the practical things (and should be) but it should not stop you from being happy and excited about having that baby, especially when we were actually trying for one.
Unfortunately his lack of enthusiasm and complete focus on money meant that when I miscarried I did not feel I had much support from him then either as to me it seemed like he did not in fact want that baby. In fact it seemed to me he was probably relieved to some extent that he did not have to stress about it so much anymore. Whether it's true or not was irrelevant. I had just lost a pregnancy that I could not have been happier to have and felt very alone in my grief.
Money is not the most important thing in the world and it was that which was lost on him at the time, so much so that he could not express that he was even remotely happy about it. It hurt.
Basically he just meant that you need to find balance in life and at that time his focus was not balanced.
