Wed,
My H did the exact same things. One day seemed totally committed, the next seemed completely disinterested in me. I remember having a MC session where I said tath I felt my needs were not being met. H got angry at that. He was being a total jerk during that phase.

The important thing is to expect that thsi will happen. He is dealing with a lot of emotions. He probably is incapable right now of tryign to meet your needs, when he's tryig to figure out how he can meet his own.

Give him time and space, but dont' be a doormat.
