A few (?) words

Had a major (verbal) fight w/son before Christmas.  He was playing Wii & getting increasingly angry & starting to spin out of control.  I told him to start playing & he got very verbally abusive with me (complete w/4 & 5-letter words).  Well, I gave it back to him & he was like, "you want to fight?"  Of course I won't do that--so I just stormed out (had to p/u my daughter anyway).  But boy, I was mad as heck!!!
And he's been getting to school later & later.  Vacation was OK.  but 1st day back, he dragged it out & dragged it out that he ended up not going.  I was furious, but didn't yell or scream (yay me!).  When I got home, he was somewhat repentant & said he'd never do that again before I even said a word.  I told him that from now on, the lunch $ he gets (which is his allowance) he has to earn by: 1) getting to school on time and 2) doing the chore I assign to him.  $1 for each, each day (which is about how much he spends on lunch). 
So guess what--he's been getting to school on time (cutting close, but doing it) & doing his chores. 
But I've also just "turned off" to him.  He has made me that mad.  No more kissing up; no more pouring on the love just for the sake of making him feeling loved.  I'm tired of his emotional manipulation.  I've had it.  My life is mine & I'm slowly taking it back.
