My boyfriend

I got mad : (
I didn't know about my boyfriends' travel.
He said "I am in Fukuoka now!"
I wanted him for me to tell earlier about the travel !!!
Why!!???

He is fun to be with. And I never have quarrels with him.
I think our problems are caused by a breakdown in communication.
I want to find an easy solution.
Please tell me about how to communicate with boyfriend > <
