We know SW suspected CW was cheating, we know she told at least 2 people about her suspicions, therefore, we know she wasn’t hiding or in denial about it. We know she wasn’t a basket case over it because she carried on with her life as usual. I compare her behavior to some friends I’ve known over the years who thought they were being cheated on, who were so distraught they became dysfunctional. Their hearts were so broken, all they’d could do was talk about him and cry for the entire length of time I spent with them. And I’m not convinced she loved him as much as everybody seems to think. They were getting near the “seven year itch” phase of their relationship. It wouldn’t surprise me if she was disappointed in him, and feeling very let down because of his lack of ambition and money making ability. SW wanted to conquer the world, CW, not so much. She may have thought she married the wrong guy, and may have grown tired of always pushing him to carry his weight, of always having to encourage and praise him to get him to do anything. She may have been coming to terms with the fact that this was a bad marriage, that they actually had very little in common.
