Lalxx - For me it is hard to draw a timeline. I know my H had a QLC about 10 years ago and I think those issues he dealt with then never did go away and were always festering in the back of his mind. In fact, when I first realized something was really wrong with him this time he said he felt like things got "swept under the rug" back then. Hopefully he is dealing with them now.
But really between then and his MLC he for the most part seemed fine, our relationship was good, etc.
