Don't act as if nothing happens. Kahit friend mo pa si Cathy, you need to talk and confront her para sa ikagagaan ng kalooban mo then after that let go and move on. Kahit gaano pa kalalim ng sugat at hapdi na dulot nito, wag mag-alala dahil lahat ng ito'y maghihilom din :) Your "the one" is yet to come. (:
