I think he got the news about the cancer only yesterday evening(judging from his reaction) but knew longer that she was feeling ill - I hadn't a clue.

I feeel constantly lied to or feel that I just get half of the story. It's the worst feeling in the world for me.
It makes me doubt our entire relationship. 9 years of my life.

You know that in my head I think sometimes that he is a serial cheater I guess because of all the unknown and all the open questions I have. That what happens when you don't have the truth - you start to expect the worst.
