She never indicates her stance on it, just that she wants to satisfy her parents and her boyfriends demands. When she says "he wants us to be able to have a wedding" it sounds like she wants this too and is only having an issue because of the parents demands. The stress of the situation with her parents is "breaking her heart completely", not the boyfriend refusing to marry her at the courthouse.
Her next post afterward says that she doesn't have an issue waiting for the marriage.
I don't think they should have a courthouse wedding out of fatherly threats if they both are young punks that want a ceremony. I don't think the guy wants to be forced to marry her with threats, even though he got their daughter pregnant, if he wants them to have a real wedding.
I'm just saying there is no harm in waiting if they truly want to enjoy the process of the marriage and do a honeymoon and all that. Yeah the formality is already thrown off with the pregnancy, but I don't see how the courthouse wedding is going to do anything at all to improve the situation. I'm giving the guy the benefit of the doubt and I also don't think a piece of paper stops someone from cheating.
