Spartan, I'm just catching up, and sorry the fight happened, but the advice everyone gave you is good: don't beat yourself too much and stop apologizing. At some point, you might want to talk about your feelings about the OM so she can see the reason for your reaction. But wait a while, until both of you are calm. You didn't ruin everything. It's just a setback.
