Marriage: For the Young or Old?

When I was young my mother always told me that I would know when I found my true love.... Kind of cheesey right....? But that's what she said and for the longest time i believed her... Until I was old enough to realize that true love isn't always happy... My husband and I, now married for about two and a half months, argue consistantley about the stupidest things. Have you and your husband argued over what you want for dinner in the grocery store? While we stand there and argue about what we "feel" like for dinner, I can't help but think that we look like idiots! In my head I can just see two little children screaming and yelling about who get to pick dinner. Is that normal? Should I expect that everytime we go to the grocery to fight? There are sometimes, like today, I just wonder was this the right decision? Should I have waited till I was done with schooling and maybe have lived on my own before we decided to get married? Do you feel that there is a right time for a couple to get married? Is there a right time in a couples relationship when they should get married?
