Does s/he throw the speaker or something to the speaker? The English translation is confusing.... :/
the indonesian part means that the speaker ("saya") is being thrown away by the 3rd person ("dia")
If the 3rd person throw something to the speaker, the correct sentence would be "Dia melempari saya "(something) eg.
Dia melempari saya sebuah bantal
S/he throw a pillow at me
