When I'm an emotional wreck is about the only time I DO read for myself. Once you find a spread you think will help you out, write out what you're getting for each card. For me, the journaling process in the reading really helps me clear my mind and see some options I may not have seen before. It calms me down, helps me focus just by the sheer act of actually doing the reading. If a card doesn't make sense, this is when I DO use my books- to get an outside objective idea of what else on earth this card can mean that I am not seeing with my own limited perspective.
I agree with SpaceDiva's line of questioning "how can I approach the situation with my spouse?" This is the kind of thing I would ask, in addition to things like, what obstacles should I look out for? What will help me get through the situation?... things like that.
Of course the Celtic Cross is very helpful in things like this, as well...but if it's too much to take on, you can just find a smaller spread or taylor one to the things you want to know.
If you do all these things people have mentioned and you still come out confused and/or frustrated, then seek out another reader. But like Zephyros said, " since I know the querent pretty well I feel I usually don't need to explain things to me"..sometimes when the reading hit real close to home, the LAST thing I want to do is try to explain to a stranger the nuances of the situation and get them to understand where I'm coming from. I already know where I'm coming from.
Best of luck to you. I hope everything turns out well xoxox
