What do you think about me staying friends with my friends ex-boyfriends?
Why would you want to stay friends with your friend's ex?
I'm planning to start dating him
Are you sure you want to do that? It would look weird if you are friends with your friends ex-boyfriend, let alone their lover. You could be violating your friendship and trust with your friend.
I don't care, he's so hot. Maybe I'll get to third base with him.
You want to really betray a good friend of yours for someone that you find hot? There will be a lot of potential boyfriends out there, but there's not a lot of friends that you can trust who you'll get to know in life. Don't mess with your friend by dating her ex, for both of your sakes.
