Moving fast or no ?

I got pregnant back in September 2014 and had my son may 31 2015 . Me and my boyfriend have been dating for almost 1 year 1/2 but I've known him for 3 years total  . He's working overtime to provide a roof over our heads and we've discussed even getting married . Would it be too fast to go to the court house and elope ? Or should I wait till he proposes and it actually be special ?
