Men has been comparing girls to clothes for centries, while I'm being generally a nice person, esp. when it comes to guys. But for those who had broken my heart... They dun hv the luck... They are mostly like clothes that I won't wear again.
I usually keep those clothes that I won't wear again, but throw away the ex. When it comes to such clothes, girls tend to be reluctunt to throw coz we've been spending time and $$ on that, and fashion may come back one day, so better keep them, though they are quite a waste of space.
But what about ex? Yes, we've spent much more time & $$ on ex, but if we dun't throw them away, they got to occupy the whole space of ur heart, no more space for the new one. What's more, they broke your heart. Clothes never broke your heart.
The question of "Can you be friends with an X" is really is "Can a broken heart be sowed even there will be a scare". It would be a "yes" if you still remember the time when he held your head when you fell asleep.
