What really worked about you and your ex
Of course there were things that worked about you and your ex. That’s why you were together for as long as you were. And while you can go into a starry-eyed, nostalgic rant to your best friend about the particular dynamic you loved between you and your ex, going into such a rant in front of your current partner will only instill deep jealousy. He isn’t sitting there taking notes on what he should do. He’s just fuming inside.
