Am I the jerk for forcing my older brother to buy me a new engagement ring after he stole

mine to propose to his girlfriend?

And I'm honestly so offended and unbelievably hurt that at this point I seriously don't know

what to do. Here's what happened.

I'm a 26 year old male and I'm proposing to my girlfriend who's 24 on our fourth anniversary

which is going to be September 30th. I've been planning this for about a month and I picked the ring out a couple of weeks ago. The one I got was on sale, so I managed to get it at a surprisingly low price.

Last weekend I told my brother about my plans and I showed him the ring.

He then informed me that he was going to propose to his girlfriend as well.

The next day, my brother came to my apartment while my girlfriend was out

and asked me if he could borrow my ring to propose to his girlfriend.

I thought he was joking at first but no. His plan was to propose to his girlfriend,

explain he was using my ring as a placeholder, and then take her to pick out her own ring later.

His reasoning was that he didn't want to spend too much money right away in case she doesn't say

yes.

I had never heard of any kind of placeholder rings, so I said no and the conversation moved on.

On Tuesday he proposed to his girlfriend and he did it with my ring.

He had taken it before leaving my apartment.

I got distracted at work and didn't notice it was gone

until his fiance sent a picture of herself wearing the ring to our family group chat.

I called him to ask about the ring and he immediately apologizes and said that he keep his promise and give it back to me as soon as possible.

But at this point my girlfriend had seen it and his fiance had posted about it on social media

so it was pointless for me to propose using the same ring.
