How to forget My ex?

[GayComputerDude]

I had a boyfriend and he is from Aussie, we were in relationship only for 6 months when he lived here in Indonesia. But before he leaved, he said wanna spent time together with me.
He went to Bali with his friend before he leaved indonesia but he took a boy from Bali to be with him. And i met them in Jakarta. I hurt so much and i just cried. He cheated on me, but i still can't forget him until now. We still in contact everday.

Tell me how to forget him!!!!!

Got no answer .. haven't talked to one of mine in months and today I did .. it made me feel warm inside

he's a good guy .. and I know it .. and think he thinks the same about me

but I have to be me and he has to be him

and if that is apart then so be it
