That's obviously a hard decision. My first instinct would be to say "Bro's before Ho's" and acting upon this once caused a riff between one of my closest friends. Eventually, he got over it and that ho got booted! BUT, 1.I knew she was a ho. 2. I know how my relationship with my bro was, so I knew that in a short while we could have a beer with him and laugh our asses off and call it good. My bro has since passed away (R.I.P.) and I still laugh and reminisce about "Debo's Girl!"
On the other hand I can see where if your friendship isn't strong enough and your "bro" is insecure (which sounds like the case), I think that everything with the bro can go south. How does the "ho" feel about the situation? Is it something possibly longterm or just a fling? How "relationship mature" are the both of you individually? Is she willing to lose the friendship with the "bro" also???
These are all questions to ask yourself about the deal.
But in all reality, You've seem to have already made up your mind.
Do what you gotta do.
