Should I refuse to take out a loan to pay for my brother’s wedding?

I know it sounds strange, and I don’t think I’m the A but I need other people’s opinions on this.

My spoiled, drop-out brother married his wife (same qualifications which is none) this year, they’re both 19. I’m 23 btw. Long story short is that my brother’s hag of a mother-in-law wants a grandkid as soon as possible so she manipulated them into getting married and my stupid mother went along with it.

My new sister in law is expecting now so I’m pretty sure my theory is correct. (No I don’t care that I’m being disrespectful.)

We’re not well off, not at all. My father who all of a sudden became a coward and didn’t talk my brother and mother out of it.

In order to pay for the wedding, my father has gotten a “loan” from my uncle, his brother, and he now wants the money back.

My parents sat me down a few days ago and they told me that they have no money to spare, too much in debt to get a loan from an actual bank and since my brother and sister in law are so young and expecting they can’t pay back my uncle either.

That leaves only me.

Apparently, because I don’t have debts, no baby is coming any time soon but since I have savings and a job, I owe it to my family to take out a loan and hand it to my uncle.

I didn’t say a word, just laughed in their faces and left. I’ve been receiving a bunch of texts and calls from my family to “save” them financially but I won’t.

I don’t know, either I live in a different reality or they do.

(No it’s not a “cultural” thing or anything.)
