i played dota once...then never touch the game, never like the game...i dont und the hype for it...

Well. I will just make it short.
Me and my bf been together for like 2 years.
He is very into Dota. When we were back in Malaysia, when his mom and dad are at home, he didnt play that much.
And even if he play, im beside him watching or sleeping.
sometimes, i slept on his gaming sofa n he will carry me to room once he done playing.
To see him, to spend time with him, I learnt to play.
sometimes when i died or feed the game, then he is very unhappy.
most of our arguments came from his games.
His temper is not that good, that's the problem.

We came Perth. and now, its getting worse.
He woke up around 4pm, then eat then go campus play dota til 430am.
Sometimes i follow him. but sometimes if there are classes next day 8am then I will stay at home.
But i feel so boring staying at home.
and I dont like waiting the door to be opened.
I cried almost everyday.
I talked to him.
I tried to make him happy.
Things are still the same.

I even told him "if you continue to behave like that, Im sorry. Im not the girl suitable for you."
He continues playing.

I couldnt stand it anymore.
what else can I do?
