How to wash one's hands of family without starting WWIII

I always figured it was a mild form of autism, (Aspergers syndrome) because I have sensory issues and some of the other developmental symptoms. Females, because females socialize differently than males, tend to fall under the radar. As a kid I was diagnosed with all of the components of Asperger's independently but no one ever put it together until I went to my family doc complaining about anxiety because I am a social loser. He said it sounded about right, and sent me to that crazy shrink that was no help at all.

After reading the Alpha Female traits I realize perhaps Im just socially an ass. I don't mean to be, but I seem to manage it none the less.. :-(

 

And an economic depression every 90... ;-)

But if you look at history there are many wars going on that we never really discussed in history class... ah but I digress...

 

But in with this thread, I have to ask this:

Night before last my hubby was rather agitated. I asked him what was bothering him and he blurted out
"Im sick of people who act like jerks getting what ever it is they want and we get {pooped} on. "M" from work makes 1200 a week, 1200! And lost his house because he couldn't make the mortgage. His wife works and makes good money too. He simply decided to spend money on junk and not on the double-wide trailer his family lives in. I dont bring that home in a month. How is that fair? He is lazy and never goes to work on time, yet there he is making that kind of money installing HVAC systems at his convenience and loses his house!"
He ranted on about this for a little while, and Im familiar with this guy and he is lazy and bad with his money. He is a customer at my hubbys shop and just blows money on expensive toys not on the things he should be paying for... Then my hubby got to the root of whats really bothering him...
"and my sister. She treats you and my mom and me like crap. She is hateful to everyone that cant do her good, and yet she gets to have this dream honeymoon and come back to a nice house and no bull crap from anyone. We got married and our honeymoon was cut short because dad was sick and she called us and made us feel bad about having gone in the first place, then we come back and had to spend 6 weeks watching him suffer and die. How is this fair? We can't even afford to take a weekend away much less a proper vacation"...
He finally calmed down and got it out of his system, but its been building for a while. Last night he apologized for his outburst, and said we needed to take a weekend away for our 5th anniversary. I try to get him to focus on the good stuff, but sometimes it all builds up.
I don't blame him for feeling this way, I dont. Its just tough to see her treat everyone so crappy and she gets whatever she wants. I have shrugged my shoulders now, I just have to get the hubby to do the same
