I have decided to call him. I made 2 calls at 1am and he didn't pick up. I decided to try one more time at 2am and he picked up. The first sentence he said: 你终于肯接我电话了啊？

Throughout the 34 minutes of call, he keeps telling how happy he is that I am still here. (Oh come on, I have left long time ago, I'm here to revenge for all the torture you put me through.) He told me a lot of lies that if I still believe them now that means I'm just pure stupid, for example: I will call you tomorrow morning (Pfft! As if I will still believe this bullshit), I miss you (you miss me?!?! You had time to do cny visit with your friends and 'no time' to contact me and you said you miss me? I really can't see which part of you are missing me), I will look for house to rent (I had heard this sentence for 482095722 times)

Do you still need to buy anything? (After insulting me and now you are asking me this question? 难道我没有自尊心吗？)

Do you have enough money? I will bank in rm1000 to you tomorrow. (You'd better pay me back whatever you owed me. In double!)

I have bought something to hold my phone in front of my computer so that we can video call which I am working. (This was part of my attempt during the final fight for our relationship but did you care that time?! then why do you care now?!)

I decided to end the call. Geram aku dengar those bla bla bla. 

But hey, you need to act well in order to get your revenge. You need to let him believe you still love him and dump him when you are at your highest point.
