A story of my friend who was dumped by her bf on CNY chu yi

They are very close and he always surprise her with gifts and all
but ont CNY, She received a message from him saying "I like my
cousin.." then she tried calling but he refuse to pick up.
I then talked to him and he said "My cousin very pretty, WAH! See
liao wanna ****"
I hung up immediately and called her to comfort her
Then my other friend told me that he was going to the cousin house
to talk about the relationship
How come he can be so irresponsible? Just end the relation like
that, Should I tell this to the cousin if they ever got
together?
