Dear Lulu Jeh: I found out that the guy I am seeing used to date an acquaintance of mine — and she is now dating my ex! Can this be any worse? Should I just end it now to save myself the headache? — Couple Swap

Oh man, CS, I feel your pain. This happens more often than you’d think in the tiny dating circle that is Hong Kong. But you do have to remember that in order to maintain happiness (and your sanity!) in any new relationship, the focus should be on the two of you, not on external factors.

The past is the past, and it’s better left alone. Try not to compare yourself with any other girl in his past. In fact, blast it from your head space completely. Focus instead on the present and have fun getting to know your new flame. — Lulu
