the start of a loooong summer

Well, today was my son's last day of school and he's already acting hideous.  He's 12 and always has to have his way or he throws a hug fit.  He got into it with his stepdad because stepdad was using the computer.  My son expects me to watch 30 min. of t.v. with before bed.  I wanted to watch something special on t.v. that was same time a his bedtime.  I told him I was going to watch this and could put him to bed like usual.  He said, "ok".  Sure enough, few minutes, before bed he starts hollering at me to go into his room for our night tv ritual.  I reminded him about our deal.  He threw a fit and I had to sit a watch his stupid tv show with him and put him to bed.  I was very angry at him a let my husband know how mad I was.  My husband got mad at me for being angry!  My husband rarely backs me up when I get into a fight.  He gets mad when my son treats him that way.   It's not fair!
I don't know if I'm going to survive this summer.  My blood pressure is already high.
