I really don't see a problem with this, and I suspect that those people wailing and wringing their hands over how 'cold' the OP is are displaying misogyny. Women are supposed to be all about 'feelings' and take no interest in the practical aspects of life.
Vast numbers of men approach marriage with the view that one woman is much like another, really, and as long as she's willing to provide domestic and sexual services and look after the DC and flatter his ego, she'll do. And women were socialised, in the past, to pick a man who would earn a good wage rather than the one with the nicest eyes or whatever, because women had to depend on men for money.
I've known a few couples where the decision to get married was more one of practicality, and they have been contentedly married for a long long time. As long as OP and her H are both content, nothing wrong with it at all.
Good sensible post.
Better than saying that those who married someone for convenience, or security, or coz they were scared of being alone, are horrible and cold, and VILE, and should never have been allowed to bear children, and SaraNade said ... 
Still gobsmacked that she cannot see anything wrong in saying that.
