Snow, I believe people rarely blow it with one or a few episodes of "losing it" with their MLCer. I don't know if it would have been good or bad to apologize for your conversation with your H.
Over the past year, I have had bad conversations with my W in the past but I cannot remember apologizing directly, i.e. I think I allowed my personality changes to come through to show who I am.
I know early on, I would apologize to her but I was all over the place and sounded so "wishy washy" and pathetic.
Keep us posted as to what is happening.
