I just don’t have—I’m happy. We’re married. We’ve got kids and a family and we’ve got to find our time together alone.  We are in it. I think if we do get married it will be for the kids, really. For us, we’re just happy. I know that’s not really necessarily a golden ticket but there is something beautiful about the security of marriage.  And we’ll get there when we get there.

They know that if they are married:

• they can pass on inheritance to a married partner, automatically in case of a tragedy or if they haven’t yet drawn up a will. If they are not married, their property could go to an uncaring family member who may have turned their backs on them when they came out the closet.

•  and in case a partner is incapacitated for illness or after an accident, or during old age, a married partner will be empowered to make decisions, not domestic partners  in most states, still

• their kids can have both their names and make permission slip signing, the names on pick up forms, and other decisions related to the kids and dealing with schools easier.

• they know that many insurance companies allow a spouse to pass over health and dental benefits to a spouse which is great if one spouse has a business, is a stay-at-home mom or dad, or works part time or is unemployed. If they are not married, the spouse without work insurance is screwed and has to get private insurance which could be costly.

• there is societal benefits to the children bearing the same names as their parents. People judge and you cannot help that so if your kid can put off stigma and judgment in this realm, great. 

• dual income and security, like Hudson said, are more likely to help than hurt a child, but with marriage comes a reluctance to just walk out in rough times. You may be more likely to work it out and try harder before calling it quits.
