Husband's can be difficult to explain to

I was fortunate because my husband's and my reading/other interests are so different and he knows he doesn't "get" mine so now when I start one of my rambling explanations about something he'll interrupt and ask, "Am I going to understand this?" and I can say "No" and we talk about something else instead.
If he asks what wrong with your life, that would be sort of easy if you just said, "Nothing is wrong with my life, I just have some problems dealing with myself and my attitude toward life" or something?
