My husband and I are not married, not in the legal sense of the word, and not in the religious sense of the word.
Marriage has become less popular because it is a religious ritual, and more people are not religious. And legally speaking there very few differences between marriage and common-law.
Also as women are more and more being paid as equals and expecting to work we don't expect a man to pay our way should a marriage dissolve. I expect that my husband (and any man) would pay a fair amount to support his children. I do not believe he should be on the hook to support me. And any potential income I have lost in the future by staying home now is also my choice, and I will live with those consequences.
Frankly it is just as easy to get divorced as it is not split up a non-marriage. The divorce rate is leading to questions of custody more than anything else. Accidental children out of wedlock tend not to have custodial issues. I know my own mother and father certainly never had any big fights over custody. They split when I was 1 and my dad got to take me every week for a day. When I was older it was changed to every other weekend. We did live in government housing where the rent was geared to income, and I think my mom got a break on daycare but she always worked, and saved. There are no food stamps in Canada and welfare isn't easy to get even for a single mom.
I grew up in a very poor section of town, were most of the kids did not have both parents. They were reasonably well adjusted, reasonably good kids. Then my mom got married and we moved to a much wealthier area. Those kids were going through divorces and it was awful. The kids were pawns in this big battle, it destroyed them mentally. It was nothing like what I was used to. I was used to custody agreements being a non-issue and the worst thing that happened was that some kids had dad's who weren't very reliable and missed visits sometime. Not this horrific psychological hurt.
We need to stop pretending that marriage is the answer, with so many marriages ending in divorce the difference between marriage and cohabitation are very small.
Having one parent, or seperated parents has no bearing on morals and values. I wouldn't have been raised religiously in any case. Neither of my parents are religious and they are both from different religions. My children never would have been raised religiously either. You may not agree with my values in that I think that there is nothing wrong with having kids out of wedlock, and that is what I will teach my children. But I do have morals and values and my children will learn them.
Also the main reason we are not married, is money. We could have spend $5,000-$10,000 on a wedding or a house. What do you think is better for our children? A piece of paper, or equity and a yard? Our house costs us less than the apartment we were living in, and that was a one bedroom. I think a bedroom, a yard, and a nice neighbourhood trump a piece of paper any day. BTW we didn't have our first child until we had lived together for 7 years and knew the relationship was working. I think that is a far cry from courtship, engagement, and then trying for kids as soon as you get married and move in together. At least I know what I am bringing a kid into.
