My husband realized I truly love him when we were in an argument. He stormed out to the shop to work and think, and I clean when angry, so I was scrubbing the devil out of the sink. In his anger he wasn't paying attention to what he was doing and cut himself on some metal. He came inside, dripping blood all over my freshly scrubbed sink. and I quietly got up, took his injured hand, and cleaned it. Then I put a bandaid on it and walked away. He said that was when he knew I would love him no matter what.
We've had plenty of arguments, and our share of bad times, but sticking it out and working it out, makes the good times even sweeter.
