The world is divided into two groups of people: those who think it's OK to date a friend's ex and those who believe it's completely off-limits.
When you and your friend are both in the "OK" camp, it can work if they date your ex, or you theirs.
From "he just doesn't get me" to "we're too different" to "why did we stay together THAT long," women tend to overanalyze past relationships.
However, the one thing that seems to be the unwritten rule among us is that we would never even consider dating our friends' exes. But now I realize this rule really needs more thought, because I believe there are two factors to consider before answering my girlfriend's Facebook question.
I'm not trying to generalize, but most of my female friends talk about past boyfriends, dissecting why their relationships didn't work.
"Once loved" are the operative words here Too often, women become territorial, trying to mark our men as if past loves are actually possessions that we own for life.
If you have moved on from this person, you really should not take issue with who they are with now.
Maintain your distance: You probably don't want to get any closer to the action than you need to, so when you're stuck in the same social scene, take the seat at the opposite end of the table, or strike up a conversation with the cute guy or girl at the other end of the bar.
Until you're comfortable with the situation, it's best to avoid confrontation -- it can only make you upset and say or do something you may regret.
