&gt; *All she needs to do is be forgiven. I'm the one who would have to work through the pain of being cheated on, the task of trying to forgive her and making sure that I mean it and ultimately going through the extremely painful task of learning to trust her again.* 

Wow.

That is one of the most profound things I have read about cheating or any other heartbreak related issue. I will definitely use this statement in the future when explaining the impact of cheating.

I wanted to respond yesterday but got wrapped up in work. What I wanted to say is that if she did this during a time of grief or high stress, then she has shown that she is incapable of making proper decisions during the most important times in a relationship. Death is a certainty, people don't use it as an excuse to make poor decisions. A person must be able to grieve as well as overcome. Relationships last not only for the good times, but working through the most difficult times also. If you have to worry about her grieving and making a huge mistakes like this during stress times in life, you will not survive.

Six years is a long time but it is not a justification to remain with someone who has betrayed your trust.
