For the love everything holy, stop talking to him.
Now, follow Liam's post break-up guide:
1) go get your hair done, and eyebrows (I'd recommend Robert Jeffrey on Halsted)
2) go buy yourself a new outfit - one in which you look fabulous
3) hit Berlin for a couple drinks
4) dance with random guys
5) go home with random guy and shag your brains out
Repeat as often as needed
