when can you say that you are really meant to each other??

Being married for 3 years with 3 kids in a row (because i have twins!), i must say there must be some differences on feelings and love shared between married couple to boyfriend-girlfriend. I used to hear my wife say I have changed. Our relationship changed. Well, maybe because hen you get married and most especially when you have children, you somehow change because your love and attention would also extend not only to your wife but also to your kids. But the great thing there is that, both of strives to maintain the quality love for each other despite the hardships and struggles of a married life. That's when you say, this girl is really meant for me..the one for me..
