I realize that we should never put expectations on people. People make promises not because they intend to break them (but as a form of reassurance); it’s just that sometimes there are volatile circumstances and they can’t anymore.
We can’t always expect things to go our way, that’s the thing that we have to manage on our own; sometimes it makes us wallow in self pity. We get addicted to that kind of ambiguity, sadness, regrets, loss and uncertainty. We often ask, why do feelings need to be so complicated sometimes?
In the end, no matter how much we want to keep something that makes us happy, we learn to let it go naturally. Until the next thing comes along.
