It's ok that you don't know exactly what to do every day. None of us do.
You are very early in the MLC process. Dealing with a MLC spouse is tough stuff even for those with some time under their belt. The mere fact that you are here seeking guidance tells me that you are doing the absolute best that you can for your W and M. Accept this and be proud of yourself!

Choose your course, and then stay on it.

Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
