However, when you're in different camps, and a friend dates your ex (or vice versa), this can lead to big trouble -- anything from awkward social interactions to permanent rifts within groups of friends.
While many would say the ideal solution is to avoid run-ins completely, in many cases it's just not possible, especially when there are overlapping friends, locations, and events.
Think objectively The fact that you broke up and your ex has moved on and is dating someone else should tell you about your ex's feelings for you.
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.
And now you feel compelled to see her in person, maybe just by showing up where you know they’ll be — right after you go shopping for a new outfit.
When you come to know that your ex is dating someone else, it crashes all your hopes of being together one day.
When you and your friend are both in the "OK" camp, it can work if they date your ex, or you theirs.
When you and your friend are both in the "off-limits" camp, it's great -- it simply doesn't happen, because you both agree it's not a good move.
Keeping your thoughts limited to this tightly knit circle will also prevent you from blabbering your opinion about the new couple to everyone.If they’ve been in the relationship for a few months or less, then it’s probably a rebound and it will end soon.On the other hand, if their relationship has been going on for over a year, then you can safely assume that the relationship is serious for them and it’s probably not a rebound.Your ex may be trying to make you jealous Your ex may be dating someone but their feelings for you have not completely gone.They might be dating on rebound but if they are still in touch with you, it could mean that they do not want to remove themselves from your life.
