Lesson of the day:
When breaking up, the woman is the one cries a lot. That doesn't prove how good of the man was nor she loved him so much that she lost herself and didn't trust herself anymore. Actually, there are many times that the woman doesn't care about how good he is, but she cares about how much time and dedication she spends on this person, how much love she feels from this man, how happy and how she feels complete when she is near him.
It's like you - yourself - struggling to build a castle, then it collapsed suddenly and you feel helplessly. Because you have tried your best to build and protect it but it can't stand still without the love from the other.
