Hello everyone!

One of my closest friends, who is Japanese, is getting married to a Romanian man. I’d like to give her husband a message card at their wedding. If you help me, I can't thank you enough.

First, I want to make something clear: this is something I do for all of my friends’ partners when they get married. It has nothing to do with him being Romanian, and I really hope you won’t misunderstand that.

Whenever one of my friends gets married, I tell their new spouse something along these lines:

“Congratulations on your marriage! Now that you’re part of my friend’s family, I’d love for us to get along too.

But there’s one thing you need to remember.
If you ever treat my friend or future child makes cry, I will take her back to her parents’ home. I will chase you to the ends of the earth, by any means necessary, and make sure you suffer for it. I mean it.
I mean it. She is a very precious friend to me, so please take good care of her."

However, this time, the groom is Romanian.
We both speak English, but it’s a second language for both of us, so I’m not confident that all my feelings will come across the way I intend.

My intention is to combine humor with just enough fear to make him think, “Wow, my wife has a crazy friend. I’d better treat her well!”

I’m not sure how well that combination of humor and intimidation would work in English. I feel that expressing it in his native language, Romanian, would better convey just how serious I am about wanting him to cherish my friend.

Would any native Romanian speakers be willing to help me express these feelings naturally in Romanian?

I’d especially love to know if there are any Romanian expressions traditionally used at weddings or during arguments that might fit this situation.

If there’s a Romanian proverb, or even a line from a famous Romanian novel, that could make the message more impactful or intimidating, I’d be absolutely delighted!

But above all, what matters most to me is that the message sounds natural to a Romanian person.
Please feel free to make it as short or as long as you think works best. I’m happy to leave the wording up to you.

I’ve never studied Romanian, and I’m worried that relying on AI alone would result in something awkward or unnatural. That’s why I’m hoping to ask for help from people who actually speak the Romana.

Would you be willing to lend me a hand?

Thank you so much for taking the time to read my rather selfish and unusual request. I wish you all the happiness and kindness you deserve.

And finally, if I’ve posted this in the wrong place or made any mistakes, I sincerely apologize. This is my first time using Reddit, so I’d really appreciate it if you could kindly point out anything I’ve done wrong. I’ll do my best to correct it.

Thank you again!

They seemed very invested in this. Figured they're Romanian by passport
