Since 9 months ago. I have a relationship with this cute awesome guy.

I love him so much.

But since the beginning he is playing this stupid game that 3 days he love me so much and care about me. Then 3 days he are so cold and indifferent then he back to the cutie stuff.

I'm dying. Many fights we had because this attitudes. But he tell me that he love me and that should I understand that he is in that way..

What should I know... I love him so much that is why still here in this relationship but what about of he never changes?
