My husband of ten years has cancer and has had quite a lot of invasive treatment which has been hard going for both of us. Our relationship has suffered and I found out a few months ago he had been messaging another woman, an old friend from school. I know there was some emotional attachments there. He has betrayed me for months and said he thinks it would be better if he left. We are trying to work things out together but I am struggling to fully trust him and driving myself mad worrying about what he has done and might still be doing. I want to confront him about things I know but this would cause another massive break down and I have to take the good times while I have them. I feel like I'm being made a fool of and am suspicious of him and his lies. Feeling lost and confused.
