Let him know what behaviors are and are not acceptable. Let him know that whatever the reason for the negative behaviors, the behaviors will not be tolerated. Punish the negative behaviors as you otherwise would.
Then talk to him about how he's feeling. Sometimes, kids just want to be heard. Let him know that he's entitled to his feelings, but that it is your choice - not his - who you bring into your life. His acting out will not change that.
And make sure to have some one on one time with your son, too. Not to talk, just to hang out together and do things. Maybe make pizza together or watch a movie and pop some popcorn. Do this on a regular basis.
