I agree with you. I get a lot of funny looks when I tell people that we've never argued. However, when they meet my wife they realize that she just won't put up with that crap. When she told me at the beginning of our relationship, "No raised voices and no arguments" I understood that it was either that way or no way, and she was worth me changing.
When I told her about the ungodly long trip up to Tacoma to get an A that she was probably never going to drive, she just rolled her eyes and started packing for the trip. That trip was enough to ruin most marriages with the horrible traffic, the horrible heat, and the long hours just sitting there as a passenger. I couldn't do it. I would have went nuts and turned into a raging you know what after a couple hundred miles. She just sat there with our dog and told me when and where to turn. When we got back home, it was 112 degrees and we all heaved a sigh of relief. She started unpacking without a single complaint. After everything had settled down, she started going through all the manuals and making copies of diagrams and highlighting important features about the A. Now, you can shake your head all you want about thirty years with no arguments, but if you met her you'd understand. I'm the luckiest guy in the world, and after one bad marriage to compare this one to I realize how fortunate I am and even though I'm a mouthy, loud S.O.B. I don't raise my voice or argue with this precious partner of mine. We discuss things, and I shut up and listen. She does the same. I know for sure that my Dad could never had said anything like this about my Mom, and I feel sorry for them both. When you have someone you cherish you let them know how much they mean to you every day. That way, if something bad happens you know 100% that did your very best to let them know how much you appreciate them. This holds true with everything, people, dogs, cats, and especially yourself.
