Even if your friend claims to not care about witnessing affection, make a point to tone it down while around him.
There's nothing wrong with holding hands or kissing, but reconsider going into a full-on dry-hump session while you're all sitting on the couch together watching We're saving the best for last, except this one is "best" in the sense that it’s the best way you’ll get excommunicated by your group of friends forever if you do it.
Pay close attention to when it is and isn’t okay to date her ex.
They’re both happy dating other people and there’s no jealousy.
I’m not saying go ahead and jump your friend’s ex right now.
It all comes down to how your friend feels about it. Remember, it’s a tricky situation and if you don’t do your homework, you could lose your best friend. If it’s been a few years and your bestie has definitely moved on, give it a go. You were a good friend and kept your feelings to yourself for long enough.
Have they been together for 10 years and just ended things in an emotionally draining way?Your friend's partner may seem awesome on a Saturday night when that's all you see of them, but a true connection (regardless of how you met) is always tougher to find.
