How do you marry someone you barely know? in Prompts

So my cousin is getting married to a guy she met 4 months ago. The time line is as follows.

She was dating some guy.
Next week she is single.
Week after she is dating some new guy.
They date for a month and a half. They’re all over each other, snogging, and hickies and I love you’s everywhere. God it was sickening.
They broke up (we all knew that wasn’t going very far).
They go away for the weekend (but wait…didn’t you guys break up?).
They get engaged
Now she is rushing a wedding.

So now my question is this:
You literally barely know him. Neither of you have a job. Or an apartment.

WHY ARE YOU RUSHING?

I obviously asked if she was pregnant. Apparently, she’s not which I dont think she is. She just isn’t like that. But then why? “Oh I love him and i know what I want and blahblahblah.”

Alright. Cool. I get it. I really really do. But, are you sure, that you really really want to commit to this person for the rest of your life when you don’t really know them?

I dated one guy for 4 years. We were engaged. And we realized it wasn’t working.
I dated another guy for 3 years. Then he left.

Like, I don’t know. Maybe, it’s just because of my personal experiences but I could never ever do that.

Sure, I’ll joke with E and be like…yeah let’s run away and get married. But would I do it? No. I don’t know him that well. I don’t know what he’s like to live with. I feel like a year isn’t enough time to really know someone much less a few months.

Would I get married after a year? yeah sure. Depending on the case obviously. Eric and I have had small fights, big fights. He’s seen my worst and I’ve seen his. I don’t think he’d hurt me. He includes me in his future plans and I include him.

But there’s still a thing where it’s like. How much do you know a person? Granted, you never know someone fully. And obviously, people change as they get older. But still. It’s mind boggling how one can commit to another after only a few months.

Good for you. I’m happy and i wish you both the best. So long as your happy with your decision I’ll support it. I won’t agree. I’ll always think you rushed. But I’ll support you in every endeavor so long as you’re doing it to make you happy.

But I couldn’t.
