Is he dragging his feet, or am i rushing things?

okay, i will try to make this as brief, yet detailed as possible. i met my guy in school almost 10 yrs ago. we were very good friends. before our last yr of school he got married an went to the army. i went my own way as well and we fell out of touch. i had 2 beautiful daughters, and one very bad marriage. his marriage didn't go to well either. my ex was violent and neglectful, both his ex wife and gilfriend cheated and used him for money.. it ended up working out that he showed up on my door step 7 yrs after the last time i saw him. by this time we both have been thru the emotionall ringer. well we hit it off. long story short, he became my boyfriend. and i became pregnant. we are extremely compatiblee. we are both very happy and loving towards eachother. we have accomplished so much together... but still yet we have only been together a yr. and our baby is only a month old... he says he dosent want to rush things because we have so far.. and i agree. but he doesn'tt even want to be engaged.. this leaves me feeling like he doesn't take me seriously. but maybe he is right. really what that little commitmentt really change.. (to me its not so little) i feel like with where we are in our lives we should be engaged.. we have good jobs, 3 kids, a new home, we are a family. im going to be starting college. i don't want to rush off to the court house tomorrow or even next month, but this boyfriend/girlfriend stuff really seems like its for high school. not 2 adults raising a family. how can i convince him were ready with out pushing him..
