the man who knows me
knows im gentle and kind
placid and indiferent
singular in mind
sees my calm, carefully controlled face
knows my temper never hot
if this man thinks as much
this man knows me not

the man who knows me
knows im grumpy, unrefined
that im scruffy and untidy
and frown all the time
sees my mood swings
bad habits ,bad temper
if this man thinks as much
this man knows me better !

I like the idea and the first 4 lines are very good.
The next four lines have a lumpy feel - compared to the 1st four - but are still good.
The second verse needs some work.
It has no punctuation. That's quite common these days, but I prefer writing with punctuation. Here's how I'd make it look - if it were my poem.

The man who knows me,
Knows I'm gentle and kind,
Placid and indifferent,
Singular in mind.
Sees my calm, controlled face,
Knows my temper: never hot.
If this man thinks as much,
He certainly knows me not!

Line 5 - to get rid of 'carefully' and tighten the line up.
Line 8 - remove the repetition of 'this man', lengthen the line and add emphasis.

If this helps - I'm pleased.
If you think, 'What does this guy know anyway? - I'd have to say, 'Very little!'
If you think, 'You bastard! You mutilator! You baby-butcherer!' - find some of mine and tell me what you think!
