gotta love the in-laws.

Jewish people can't wear cross necklaces?

They don't believe the saviour (Like Christian Jesus) has come.

I do

I do

Sounds like such a nice person :/

Well, she crossed you, that's for sure.

passive aggressive much?

I'm sure you will go up in flames if you wear it ...

If you are marrying a christian man, why even get all worked up about such minor details?

I don't think OP is "worked up". She did describe the necklace as "beautiful" after all. But it is kind of embarrassing (for lack of a better word) to have your future in-law not know your religious beliefs. :)

I saw that. But posting that here as an FML kind of suggests that she's upset about it.

Maybe mom in law has an agenda.
If OP is marrying a christian man, maybe mom in law was doing that, to welcome her into the family and community.
The FML tells me OP's not willing to integrate.

maybe it was a (bad) mistake? or maybe she didn't intend the cross to mean anything, just looks nice?

Well your people killed Jesus so wearing the necklace will be a way to say that you are sorry for you ancestors.

You should wear it to show that you are sorry for your ancestors' sin.
