It all depends, depends on how long it's been since your friend dated this guy, depends on how your friend feels about it too.
I dated one of my cousins ex once and she was perfectly ok with it. Of course, they dated for 2 ys when she was 13 and he was 17; he asked me out when I was 21 (I'm 2½ ys older than my cousin), so, it had been a while and by this time she was dating a guy she loved dearly and actually preparing her wedding.
But I didn't just jumped into it because of all this facts, inspite of all I asked her and my uncles if they wouldn't feel offended, they said there was not a problem and so I dated the guy.
Even though he is a super nice guy, we didn't last much, because I wasn't entirely comfortable with the situation.
But I can tell you that one of my cousins is now getting married to another cousin's ex (big twisted family we are LOL), but same thing, it's been so long and the one he dated first is happily married, has 2 beautiful kids.
The thing is, as big as the world is, sometimes you can't help stuff like this to happen.
