I try doing the bro code you step back because your friend likes this girl. What ***** is she likes you but you fight temptation. Respect your friend even when they make you out to be the bad guy.
If you get the girl you lose a friend sometimes the girl loses interest and your stuck with no one. Trying to do what's right and honorable even if you end up alone. You don't want anyone talking about you or thinking less of you. By staying out of it and not getting involved with the drama that has nothing to do with you.
The worst is a friend that thinks because it's yours they can take it or entitled to what's not there's. Those kind of people get let go because the drama isn't worth it anymore.
She you love her you'll fight if she's noble and honorable she's worth it. If you don't trust her or can't be yourself.
After a while you get tired of changing for someone that's always the same. You enable their toxic that grows and destroys you breaking your heart and kindness.
