I know it sounds super cliche, but it's about communicating better and accepting that people change along with the relationship.

Never projecting your anger and your sadness to your partner no matter how long your relationship is. Serius deh, capek tauuuuuuuuuuuu.

Thinking back, I realized that I kept going back and forth trying to abruptly show my feelings because I was afraid that he wouldn't provide any feedback. That's not right. When you love someone, you shouldn't wish for any feedback, no? Also, communication is really THE key. I found out that I'm quite hard to keep up with updates while he always managed to do that no matter how busy he was. Perhaps, I should try to love someone more properly next time, unconditionally devoting myself to them.

if it’s not meant to be, don’t force it.

We are always the bad ones in someone’s story, even though you have done your best for your relationship.

Never give a chance to a narcissistic, once you find that person is a narcissistic, immediately leave them!

communication is not enough to keep things afloat, comprehension and effort are.
