It must have been AT LEAST a month since we had this thread.
Nearly all my friends are of the opinion that this is one of the worst things you can do, and believe that their exes are completely off-limits and expect others to follow suit.
I think it's bullshit, and would be more than happy for one of my friends to get with an ex if it made them happy. Would even go as far as to actively encourage it. (Barring some extreme circumstances during the break-up, I guess).
It's probably because I fancy all my friend's girlfriends a little bit, and usually get on well with them, maybe because I subconsciously know nothing's going to happen because they're with my friends.
What do YOU think?
