The moment this relationship becomes public, your friendship changes permanently. Even if the breakup between your friend and his ex was amicable, your new alignment creates a sense of betrayal. You must evaluate whether you are prepared to lose this friendship entirely, as many people consider dating a friend’s ex an unforgivable breach of the "bro code" or basic social loyalty. The Question of Timing
I once interviewed a man (let’s call him "Mark") who married his best friend’s ex-girlfriend. Mark justified it for years. "He was abusive. He cheated first. She needed saving."
If they recently broke up, she may be reaching for the closest, safest familiar face to cope with her pain. Rebound relationships born out of trauma rarely survive long-term.

Can you salvage anything?
Avoid going to the same spots, bars, or hangouts that defined her previous relationship. Build entirely new routines, find new favorite locations, and cultivate a fresh social network together. The Question of Timing I once interviewed a
Do not let him hear the news from someone else or social media. Sit him down privately, explain the situation with maturity, and take accountability for the awkwardness. Expect him to be angry, hurt, or confused.
Is this a "best friend" or a casual acquaintance? The closer the bond, the higher the emotional stakes.
Never let a friend find out through social media or "the grapevine." Have a direct, private conversation.
