Deception.
Something is wrong, but don't 'hit grass alarm snake.' (ta cao jing
she)
Trashing when you
have little information about who and what's going on is at your
disadvantage. Appear as if nothing happens, first. If you
boyfriend/husband knows that you receive the message, generally, I
can bet you, he will do one of these few things:
I) Explain to you before you even ask him. Under MTG, this is
called First Strike. Listen to his story and check out his body
language. Few experts who lie, are good at concealing body language
and knowing how to spin a good tale at the same time.
II) Plan his words already, but choses not to initiate the
explaination. If you were to question about it, then he will speak.
Therefore the plan is act normal. If he falls under this category,
you will feel that he may treat you a little nicer than usual.
Under Theory of Y&Y, whats negative are balanced by positive.
If he is gulity, he will replace the gulit by treating you better
to minimize this gulity to a significant balance. Unless your
relationship is already rocky beyond hope of redemption, then
usually, he wouldn't go such measures to conceal things - he just
wants to go. 
III) He wouldn't initiate his explaination like above, but when you
question him about it. He will blast and throw temper OR he will
simply admit certain things. Usually, under this category, he
wouldn't even bother to treat you better because he already wants
to leave the relationship (like explained above)
P.S: Think smart, act blur.
Cheers
