Weird how actively repeatedly cheating on your SO causes them to leave you. Who would have thought 🤔

>For some reason I decided to use my uncle’s helmet from the germans in ww2

Was that reason your undying love and empathy for the original wearer?

>another group of students decided to dress up as jews. At first we tought that it was funny so we played along and took a few silly photo’s.

So you went low and found a way to make it worse along with your bizarrely tasteless classmates?

Honestly all of this sounds planned, deliberate, and very non-accidental, and the only reason you're online trying to fish for support is that someone likely pointed out that laughing at human atrocity and making fun of genocide and war crimes are not good looks.

>a lot of people thought that we had planned this and now, am I and the students who dressed up as jews seen as racists by the rest of the school. What should I do to restore my reputation?

You did plan this and lying after the fact can't change your wilful decision to mock a horrific historical event and showcase your racism and pro-racist stances. You proudly wore the outfit. You smiled and posed for pictures. Zero of this happened by accident.

I hope no one forgets how you allied yourself with the scum of history.

Yes, tell her then buy her a mini safe to keep her contraception in so her baby fever parents don't make decisions for you.
