I'm not married but have a baby, me and the baby's father are together - decided that buying a house together would be a better use of our money than getting hitched. Our child has a stable home life, and people around who love and care for her - what else matters?
Anyway, I don't believe that marriage is for everyone, whats the point anymore? it used to mean something but nowadays it's mostly just an excuse for a few parties! I know 3 couples who married and split within a year - What a waste of money!
