Marriage

I like the idea that two people go to a commitment to live together for a period, they share all their life including their money, etc… I call it marriage. but as we change during the time I right now do not like to sign such a contract for more than 5 years, but I can love someone for my life time! but if 2 person want to have children (that is not my case) they should sign a contract to grow their child at least for about 15 years, base on a research on “biology of love” a man can fall in love biologically few times in his life.
