I have found that it is true, especially when you are so young. My boyfriend (now Ex) was extremly excited when i came home to tell him that i was having his child, I was 15. And when i was in the delivery room, giving birth to a 8 lb. 7 oz 17 in long child, he was out with a girl that he had been sleeping with for almost my whole pregnancy. Be careful what you believe, but then again I am pregnant now and my finace and i couldnt be more happier, and he is sticking with it, he is nothing like my Ex.
