Thanks for the replies! My wife's sister is 27 years old, has never had a drivers license, no job, and her house is so disgusting, I won't even allow my kids to go over there. She still drives around all over town with no license or insurance on their car. I just can't believe that she doesn't get caught. I can't relate to her husband because he's the same way. This behavior and their filthy house seems to be okay with him.
I don't think my wife or her sister had a traumatic childhood or anything. They were both close to their parents. But they were slobs too. My mother in law died last September, and the problems my wife has with her dad now, stem from that. He was seeing somebody else as she was dying.
Anyways, my wife's behavior around the house or towards me hasn't changed due to any of that. This was going on long before any of the stuff with her parents happened.
To the second reply, I don't really know what to say about that. I have never given my wife anything to be angry about. You say that it's silly to get a divorce over laundry not being done and stuff like that. It goes a little deeper than that for me. I have worked really hard to improve our situation. I work hard all the time. When I come home, I take care of stuff around the house like mowing, fixing things, and I'm always doing something. I have provided a nice, comfortable living for my family. I encourage her to do something with her life. Instead, when she lays around on the couch all day instead of doing ANYTHING AT ALL to help out around the house or contribute to our marriage somehow.... to me, that's like a big F you to our wedding vows. It's insulting. I should not have to totally support another adult because they are lazy. If she were sick or something, that's different. But she's perfectly capable of helping me out, and she doesn't. She doesn't apologize for anything, won't ever listen to me without blowing up in my face, and won't get help. I mean, what other options do I have? Continue to put up with it? I'm sick of it.
