courthouse marriage??

Elaine.
Looking for opinions... so me & my boyfriend just found out I'm pregnant... he says he's glad I'm the one blessing him with a baby & all that, 
He says he wants to marry me.. but getting married costs money... 
would I be wrong to suggest a courthouse wedding? & the reception or whatever later? 
I feel like if he can put a baby in me, he should be able to marry me... am I right?
