He Is Angry All the Time

I have finally noticed some type of pattern to my husbands mood and outburst. He is 48 years old and he is angry at me most all the time. We have been married for 20 yrs. But I have gotten to the point that I almost don't care what he does. Nothing I do is ever right when he gets like this and nothing I have ever done has made the phases shorter or more easy to deal with. His daughter was diagnosed as bi-polar and anti-social and I am beginning to think that he was not diagnosed when he was younger. Back then it was handled as "boys will be boys" but there is definitely a pattern to these outburst. My 18 yr old son has noticed the same thing and has come to me about it. It is obviously to others but he thinks that I am going behind his back to these people and talking about him. He doesn't think they can see it for themselves. Grant it, it has taken years to notice the pattern, but it was there all along. He goes through one of these about 2-3 times a year for about 3-4 weeks when he wreaks havoc with our emotions. He always starts a very large project during this time and I mean large projects like building carports or painting our two story house and re-wiring it at the same time. He is always right and everything I do is always wrong even if it is something as simple as washing some clothes he had thrown down by the bed. He sleeps is another room or on the couch and rants about how I never have anything to do with him.

I am wondering if this is a symptom of any type of mental illness that anyone can put a finger on. I want to think antisocial or bi-polar but the rest of the main symptoms are not there. Help!!!!!!
