If bros before hoes is applied among us, why none of my friends cover up for me?

This applies among us but none of my close friends sided with me when I cheated on my girlfriend of 3 years. None of them wanted to cover up for me.

One wanted me to confess and others simply said they wouldn't support me in the cheating nor lie to her if she ask. I ended up confessing and obviously she dumped me. Supposedly we have each other's back, we support each other but suddenly none took my side on that.

Ironically some of them don't mind sleeping around when single. They got no issues with that. So why wouldn't they cover up for me?

I could understand if it was a female friend... she would obviously tell the girl. They support their own kind but my male friends didn't supported me in covering up for me. My own kind didn't sided with me on that one.
